I woud like to ask you a question regarding of installation of Rainflow package from this site: https://github.com/AmritaLonkar/rainflow-octave
I should be this https://de.mathworks.com/matlabcentral/fileexchange/3026-rainflow-counting-algorithm modified Matlab package for Octave, but it does not work.
Installation is written here, but I am not able to do so. I am NOT a programmer, so I would like to ask you for help and detailed procedure of installation.
Compilation and installation for GNU Octave
Do the following to create a compiled mex-file from "rainflow.c" and to test the result:
$ cd ./rainflow-octave$ make$ ls ./src/rainflow.mexrainflow.mex$ make test
Move files: rainflow.mex, rainflow.m and sig2ext.m to a place where GNU Octave can find them.
Octave will locate oct- or mex- files automatically if they are in a directory listed in the search path. To figure out the search path, do:
$ octaveoctave> path Octave's search path contain the following directories:
.
/usr/local/share/octave/site-m
Please do not hesitate to ask more questions if needed.
Best regards

My system
OS: e.g. **Windows 10
Octave version: e.g. Version 6.1.0
Installation method: e.g. Downloaded" from https://github.com/AmritaLonkar/rainflow-octave
I was able to build and run the rainflow package just using Octave 6.2.0 on my Windows 10 system.
Octave is capable of performing some compilation internally in order to build packages. I have no idea how to use the rainflow tool once built, but the following process worked to create it:
download the rainflow source tree and unzip it to it's own folder. This is normally the purpose of the git program mentioned above. It downloads and manages source code. Instead, manually download the source code.
Start from the rainflow page
click the Green button that says Code
click Download ZIP, save the file in a folder named rainflow where you'll be able to find it again. I used C:\Octave\rainflow\.
Now open Octave. You can use the pkg tool to build an installable package from the downloaded source code and then install it. This package is simple enough that the Octave-Windows environment is sufficient to perform the build:
in Octave, use either the cd command or the folder tree in the upper left of Octave to navigate to the folder where you saved rainflow. In my case, using the cd command I would type cd c:\octave\rainflow\. Yours might be different.
the only file in that folder should be rainflow-octave-master.zip
now, use the pkg tool to compile the package using the command pkg build . rainflow-octave-master.zip (the . means it will save the package in the current folder.)
When it finishes there should now be a second file in that folder named rainflow-1.0.2-x86_64-w64-mingw32-api-v55.tar.gz
install the package using the command pkg install rainflow-1.0.2-x86_64-w64-mingw32-api-v55.tar.gz (It will give some warnings about documentation, but the package should still install.)
verify installation by listing installed packages using the command pkg list. you should see rainflow in the list of packages. if not, try pkg rebuild then another pkg list. In my case, I see partway down the list:
rainflow | 1.0.2 | C:\Users\USERNAME\octave\rainflow-1.0.2
You can now use the package by first loading it using the command pkg load rainflow.
Testing it out a bit:
octave:76> rainflow
error: rainflow: RAINFLOW requires at least one input argument.
octave:77> rainflow(1)
ans = [](3x0)
octave:78> A = magic(3)
A =
8 1 6
3 5 7
4 9 2
octave:79> rainflow(A)
ans =
0.5000 2.0000 0.5000 0.5000 3.5000
3.5000 3.0000 8.5000 6.5000 5.5000
1.0000 1.0000 0.5000 1.0000 0.5000
The only issue I see is that afterward help rainflow does not show the help from rainflow.m, I suspect it should be included in the rainflow.c file. maybe this has to do with a change in octave since rainflow was created? if you want to read the help, you need to navigate to the package installation location or the location of the source files you unzipped and type help rainflow, at which point it will show:
octave:49> help rainflow
'rainflow' is a script from the file C:\octave\rainflow\src\rainflow.m
RAINFLOW cycle counting.
RAINFLOW counting function allows you to extract
cycle from random loading.
SYNTAX
rf = RAINFLOW(ext)
rf = RAINFLOW(ext, dt)
rf = RAINFLOW(ext, extt)
OUTPUT
rf - rainflow cycles: matrix 3xn or 5xn dependend on input,
rf(1,:) Cycles amplitude,
rf(2,:) Cycles mean value,
rf(3,:) Number of cycles (0.5 or 1.0),
rf(4,:) Begining time (when input includes dt or extt data),
rf(5,:) Cycle period (when input includes dt or extt data),
INPUT
ext - signal points, vector nx1, ONLY TURNING POINTS!,
dt - sampling time, positive number, when the turning points
spaced equally,
extt - signal time, vector nx1, exact time of occurrence of turning points.
See also SIG2EXT, RFHIST, RFMATRIX, RFPDF3D.
those other functions appear to be included as well and the help works, so you can try help sig2ext, help rfhist, help rfmatrix, and help rfpdf3d. I have not tested to see if they all actually work. But this will get the package up and running for you to start using. Good luck!
This worked for me. I'm on linux, but process should be the same on windows.
mkdir TempFolder
cd TempFolder
git clone https://github.com/AmritaLonkar/rainflow-octave.git
cd rainflow-octave
make # for some reason this places the .tar.gz package in the PARENT folder
cd .. # so let's go there
octave # and let's start octave from this directory
now from inside octave:
pkg prefix /path/where/you/want/the/package/to/be/installed
pkg install rainflow-octave-1.0.2.tar.gz
pkg load rainflow # to load the package and test it
rfctest # run the test to ensure it works
I've created a HTML5 project in the old Cloud 9. I've migrated it to AWS Cloud 9. Now when I select "Run", I get an error, where previously a new tab opened starting the website. How do I fix this?
The error I get is:
bash: line 1: index.html: command not found
Process exited with code: 127
Fixed it. I had to change the runner to PHP (Build-in web server)
I'm trying pyqtdeploy for the first time, following the docs.
I'm getting the following error when running build-demo.py:
C:\Users\Administrator\AppData\Local\Programs\Python\Python36-32\Lib\site-packag
es\pyqtdeploy\demo>python build-demo.py
pyqtdeploy-sysroot: Unable to detect MSVC2015 or MSVC2017.
The py file seems to be getting Environment variables from the os module, as running the same command in python console it works fine. Somehow pyqtdeploy is having a problem with this.
I have the build tools installed in the system; what am I missing here?
You must search the location of the vcvars64.bat in your Build Tools' folder location and copy it. It depends on your system environment and the version of Visual Studio installed.
Before run pyqtdeploy script, paste that location in the command prompt. This will initialize the Environment and enable the detection of MSVC x64.
Step 1 : Download all the required packages ....
pic1
Step 2 : Browse to the directory where Micosoft Visual Studio is installed
pic2
Step 3: Search for vcvars64.bat in that directory
pic3
Step 4 : Run vcvars64.bat and if it successful, run pyqtdeploy-sysroot sysroot.json

What is the full workflow to make the ioncube fully function, and each time I push the repo data won't not deleted / reset?
I do read about
https://www.openshift.com/forums/openshift/how-to-install-ioncube-loader
But not really clear for the step.
Credit to cdaley: https://www.openshift.com/forums/openshift/how-to-install-ioncube-loader
First, you have to have created a gear with the Zend cartridge. (why? because you can go to zend/configuration/etc/php.ini to add the php.ini setting)
ssh into your gear and cd app-root/data
wget http://downloads2.ioncube.com/loader_downloads/ioncube_loaders_lin_x86-64.tar.gz
tar -xvzf ioncube_loaders_lin_x86-64.tar.gz
You will end up with a
folder called 'ioncube'
Run echo $OPENSHIFT_DATA_DIR and make note of the output
nano $HOME/zend/configuration/etc/php.ini
Add this line to the END of the file you are editing (this one depend your php version, can be 5.3, 5.4, 5.5 or even latest version)
zend_extension=<OPENSHIFT_DATA_DIR>ioncube/ioncube_loader_lin_5.3.so
Where you replace with the path from Step 6.
Put the loader-wizard.php into your $OPENSHIFT_REPO_DIR/php directory
Exit out of your ssh connection
Run rhc app restart $appname where $appname is the name of your application OR you can restart on the web console.
View the $appname-$domain.rhcloud.com/loader-wizard.php in your browser and it should say that the extension is installed correctly now.
I can't figure out why my RMySQL package won't install - here's what I get:

Warning message:

I don't think it's a problem with the MySQL install, as the right values seem to be in the registry:

MYSQL_HOME "C:/PROGRA~1/MySQL/MYSQLS~1.1/"
> readRegistry("SOFTWARE\\MySQL AB", hive="HLM", maxdepth=2)

Puzzled. Any help would be greatly appreciated!
The basic process is described here, but there are several hints, So I will describe the whole solution (please change the R version and paths if needed):
Install latest RTools from here
install MySQL or header and library files of mysql
create or edit file C:\Program Files\R\R-2.12.1\etc\Renviron.site and add line like MYSQL_HOME=C:/mysql (path to your mysql files)
copy libmysql.lib from mysql/lib to mysql/lib/opt to meet dependencies.
copy libmysql.dll to C:\Program Files\R\R-2.12.1\bin or to windows/system32 directory.
run install.packages('RMySQL',type='source') and wait while compilation will end.
This worked for me on Windows 7 64 bit, so there should be no problems with 32 bit versions
Initialy posted here (similar question).
First I would try following the directions on this page: http://biostat.mc.vanderbilt.edu/wiki/Main/RMySQL
Then, ensure that you actually have a MySQL client on your computer, not just the server itself. I've had a problem myself where I had to use an older binary for the client, but you can download these from mysql website.
I created a binary which might work for people:
http://kenahoo.blogspot.com/2011/09/rmysql-binary-for-windows-7.html
I basically followed all these directions, including the ones at the Vanderbilt page, but for one reason or another it doesn't always seem to work. Anyway, hope this might be helpful for people who have the same versions of stuff I used.
I was having this same problem on Windows 7 with R 2.12.1 x64 and resolved it by:
Changing the R directory in my PATH variable to C:\Program Files\R\R-2.12.1\bin\x64 (rather than just ...\R-2.12.1\bin).
Copying ...\MySQL Server 5.5\lib\libmysql.dll to ...\MySQL Server 5.5\bin\.
Running R CMD INSTALL RMySQL_0.7-5.tar.gz in cmd.exe (install.packages('RMySQL',type='source') in R still would not work).
I came across this step-by-step guide to install RMySQL under Windows7 64bit.
http://www.ahschulz.de/2013/07/23/installing-rmysql-under-windows/
The software I used are:
Windows 8 OS
R3.0.2 - 64bit
Rtools 3.1
MySQL Server Community Edition 5.6 - 64bit
Following the above guide (with screenshots provided), my installation and loading of the RMySQL package works.
Many thanks to Arne Hendrik Schulz!
As Marek said. There is no windows binary for this package. I had similar troubles on my Mac when I tried to install RPostgreSQL (because there's no binary for Mac) in the end I had to compile it on my own and modify several files.
For the MySQL part(if you don't know much about MySQL), you might want to use WAMP which is admittedly more than you need, but easy to install and to start and shut down.
For some compiling help you might be interested in Rtools
HTH
BTW: What kind of windows do you run (sry, if I missed it)
You however there is one additional requirement at present (with the MySQL server version 5.5 & R2.12.1) follow thehttp://biostat.mc.vanderbilt.edu/wiki/Main/RMySQL instructions at present as the locations of the libmySQL.dll differs to what is expected in the package.
i.e. for the 64bit compiling.
it expects the libmySQL.dll to be in "${MYSQL_HOME}"/bin/libmySQL.dll
so simply copy the dll over to the /bin dir and it will now compile.
for the 32bit compilling.
the libmySQL.lib is expected in "${MYSQL_HOME}"/lib/opt/libmysql.lib
again moving this should solve the problem.
Alternatively, if you don't want to or can't move these files. Then you can edit the source code files:
Makevars.win
Makevars.win32
Makevars.win64
appropriately pointing to /lib/libmysql.dll /lib/libmysql.lib
Add MySQL and RTools directory to the PATH!
Here is my PATH ; ~blah~;C:\Program Files\MySQL\MySQL Server 5.5\bin;c:\rtools\bin;C:\Rtools\gcc-4.6.3\bin;
I was working for last 2 days on Installation of R with RMySQL package, finally got the solution for that, here are the steps to install RMySQL package:-
DOWNLOAD SOFTWARE FROM THE FOLLOWING LINKS:
*a. R2.13.2: Download R from http://cran.stat.sfu.ca/index.html
b. RTools 214: Download RTools from http://cran.cict.fr
c. RMySQL 0.8-0.tar.gz: Download RMySQL from
http://biostat.mc.vanderbilt.edu/wiki/main/RMySQL/RMySQL_0.8-0.tar.gz
d. MySQL Server 5.0: download it from http://dev.mysql.com
e. RSTUDIO (optional): download it from http://rstudio.org*
SET THE FOLLOWING ENVIRONMENT VARIABLES
* a. MYSQL_HOME : <drive>/path to MySQL installation folder
e.g. MYSQL_HOME= C:\Program Files\MySQL\MySQL Server 5.5\
b. R_HOME: <drive>/path to R installation
e.g. R_HOME=C:\Program Files\R\R-2.13.2\
c. PATH: Modify path to accommodate the above variables. *
Be sure that the following paths areincluded in your Windows PATH variable:
\Rtools\2.14\bin
\Rtools\2.14\MinGW\bin
\Rtools\2.14\MinGW64\bin
CREATE FOLDER AND COPY FILES
a. OPT: Create a folder OPT under C:\Program Files\MySQL\MySQL Server 5.5\lib and copy
MYSQLLIB.LIB the above path. Also copy libmysql.dll to \\R\R-2.14.0\bin\ (64 bit) Or \\R\R-2.14.0\bin\i386\ (32 bit) and to C:\Windows\System32.
b. Renviron.site: create or edit a file \\R\R-2.14.0\etc\Renviron.site and add a
line: MYSQL_HOME =”C:/Program Files/MySQL/MySQL Server 5.5/”
NB: USE FORWARD SLASH AND DOUBLE QUOTES HERE
c. libMySQL.dll: Copy this file to C:\Program Files\R\R-2.13.2\bin\i386 as well as C:\Program
Files\R\R-2.13.2\bin
RUN COMMANDS
a. Install.Packages: Run R GUI by clicking on the R icon on desktop or from Start menu. Type
INSTALL.PACKAGES(“RMySQL”,type=”Sources”). This will download the required software from repositories.
b. Command Prompt: Copy the downloaded zip file (in step 4.a.) and paste it under R
installation folder. Go to start menu and open Command Prompt. Go to the R installation folder and type R CMD INSTALL RMySQL_0.8-0.tar.gz
*COMMANDS:
>library(RMySQL)
>drv = dbDriver("MySQL")
>con = dbConnect(drv,host="localhost",dbname="test",user="root",pass="root")
>album = dbGetQuery(con,statement="select * from t_master")
>album*
18 months later, new laptop, same problem. Returning to the scene of the crime - sorry January 2011 self; we're in the future, and this installation still isn't any fun.
Lessons learned:
-Updated RTools are essential. Get them.
-Are you seeing an error along the lines of .onLoad failed in loadNamespace() for 'RMySQL', details? This seems to mean that there's a problem with your system environment variables.
In R, run
Sys.getenv('MYSQL_HOME')
If it spits back a path like
[1] "C:\\Program Files\\MySQL\\MySQL Server 5.6"
you're good. But if it gives you empty string, you need to set this.
These are all Windows 7 directions, but the process is pretty similar in XP, if memory serves.
1) Bring up System Properties > Advanced > Environment Variables.
2) In the lower 'System Variables' pane, click 'New'.
3) Variable name is MYSQL_HOME and value is whatever the path is to your MySQL installation - mine was C:\Program Files\MySQL\MySQL Server 5.6
Newer versions of MySQL don't seem to create an environment variable on install - that and the lack of binaries for RMySQL explain why this questions has garnered 8,000 hits.
-Still stuck? Here are two additional in-depth writeups: 1, 2
Following worked for me in red hat linux
wget http://cran.r-project.org/src/contrib/RMySQL_0.9-3.tar.gz
