So here's the code in Julia
using CSV
using DataFrames
using PlotlyJS
df= CSV.read("path", DataFrame)
plot(df, x=:Age, kind="box")
#I DO get the box plot for this one, because in the csv that column is headed with "Age"
plot(df, x=:Annual Income (k$), kind="box")
ERROR: syntax: missing comma or ) in argument list
Stacktrace:
[1] top-level scope
# none:1
#here I get an error asking about syntax, but I don't understand since the x= part is exactly what the column is labeled. If I try 'x=:Annual' I get a box plot of nothing, but the column title is "Annual Income (k$)".
Help is greatly appreciated!
Refrence: https://plotly.com/julia/box-plots/
Try:
plot(df, x=Symbol("Annual Income (k\$)"), kind="box")
The : syntax constructs a Symbol, but only upto the next space. So :Annual Income (k$) says to build the Symbol Symbol("Annual"), but then leaves the Income (k$) parts dangling. Instead you can explicitly construct the Symbol yourself like above.
The backslash before the $ symbol is because Julia uses $ usually for interpolation, and here we want to use the raw $ character itself. You can also do plot(df, x=Symbol(raw"Annual Income (k$)"), kind="box") instead, as no interpolation happens inside raw"" strings.

i am trying to compare two csv file data and followed below process in RIDE -
${csvA} = Get File ${filePathA}
${csvB} = Get File ${filePathB}
Should Be Equal As Strings ${csvA} ${csvB}
Here are my two csv contents -
csvA data
Harshil,45,8.03,DMJ
Divy,55,8,VVN
Parth,1,9,vvn
kjhjmb,44,0.5,bugg
csvB data
Harshil,45,8.03,DMJ
Divy,55,78,VVN
Parth,1,9,vvnbcb
acc,5,6,afafa
As few of the data is not in match, when i Run the code in RIDE, the result is FAIL. But in the log below data is shown -
**
Multiline strings are different:
--- first
+++ second
## -1,4 +1,4 ##
Harshil,45,8.03,DMJ
-Divy,55,8,VVN
-Parth,1,9,vvn
-kjhjmb,44,0.5,bugg
+Divy,55,78,VVN
+Parth,1,9,vvnbcb
+acc,5,6,afafa**
I would like to know the meaning of ---first +++second ##-1,4+1,4## content.
Thanks in advance!
When robot compares multiline strings (data that has newlines in it), it uses the standard unix tool diff to show the differences. Those characters are all part of what's called a unified diff. Even though you pass in raw data, it's treating the data as two files and showing the differences between the two in a format familiar to most programmers.
Here are two references to read more about the format:
What does "## -1 +1 ##" mean in Git's diff output?. (stackoverflow)
the diff man page (gnu.org)
In short, the ## gives you a reference for which line numbers are different, and the + and - show you which lines are different.
In your specific example it's telling you that three lines were different between the two strings: the line beginning with Divy, the line beginning with Parth, and the line beginning with acc. Since the line beginning with Harshil does not show a + or -, that means it was identical between the two strings.
I am trying to read a csv file in octave. The file contains a table with both numeric and text data. It also contains information of date and hour. In addition, the first line is in a different format then the rest of the lines since it contains titles.
The csvread can only read numeric data (according to Octave help), so I tried using xlsread as follows:
[NUMARR, TXTARR, RAWARR, LIMITS] = xlsread ('Line.csv')
I get only a matrix of NUMARR with numeric values. However, all other returned variables are empty- their dimension is 0x0.
How do I get all the text and all other information?
TX!
To solve this issue, open your CSV file in Windows notepad and save it as ANSI format instead of UNICODE.
Im trying to generate an xtable of a .csv file within a knitr document. The csv file contains cells which have several math symbols such as '±'.I do not know how to tell xtable to include that math symbol within the knitr document.
Thus far i have been trying the following
table<-read.csv("table.csv",check.names = FALSE)
q<-xtable(table,
caption = "This is my table",include.rownames=FALSE,label="tab:table")
print(q,include.rownames=FALSE)
This doesn't work and gives me the following error "missing $ inserted"
Thank you in advance
The fact that you read in a CSV is irrelevant. It is a data.frame after read.csv().
The result of xtable() can be post-processed as illustrated on the help page. However, if these math symbols appear only in a column or two, it is easier to pre-process your table, wrapping the cell entries in $ ... $.
e.g.,
table[,1] <- paste0("$", table[,1], "$")
I'm mostly at a loss for how to describe this, so I'll start with a simple example that is similar to some JSON I'm working with:
"user_interface": {
username: "Hello, %USER.username%",
create_date: "Your account was created on %USER.create_date%",
favorite_color: "Your favorite color is: %USER.fav_color%"
}
The "special identifiers" located in the username create_date and favorite_color fields start and end with % characters, and are supposed to be replaced with the correct information for that particular user. An example for the favorite_color field would be:
Your favorite color is: Orange
Is there a proper term for these identifiers? I'm trying to search google for best practices or libraries when parsing these before I reinvent the wheel, but everything I can think of results in a sea of false-positives.
Just some thoughts on the subject of %special identifier%. Let's take a look at a small subset of examples, that implement almost similar strings replacement.

.NET Composite Formatting
The .NET Framework composite formatting feature takes a list of objects and a composite format string as input. A composite format string consists of fixed text intermixed with indexed placeholders, called format items, that correspond to the objects in the list. The formatting operation yields a result string that consists of the original fixed text intermixed with the string representation of the objects in the list.

SharePoint solution Replaceable Parameters
Replaceable parameters, or tokens, can be used inside project files to provide values for SharePoint solution items whose actual values are not known at design time. They are similar in function to the standard Visual Studio template tokens... Tokens begin and end with a dollar sign ($) character. Any tokens used are replaced with actual values when a project is packaged into a SharePoint solution package (.wsp) file at deployment time. For example, the token $SharePoint.Package.Name$ might resolve to the string "Test SharePoint Package."

This is a bit of a .json file I need to find information in:
"title":
"Spring bank holiday","date":"2012-06-04","notes":"Substitute day","bunting":true},
{"title":"Queen\u2019s Diamond Jubilee","date":"2012-06-05","notes":"Extra bank holiday","bunting":true},
{"title":"Summer bank holiday","date":"2012-08-27","notes":"","bunting":true},
{"title":"Christmas Day","date":"2012-12-25","notes":"","bunting":true},
{"title":"Boxing Day","date":"2012-12-26","notes":"","bunting":true},
{"title":"New Year\u2019s Day","date":"2013-01-01","notes":"","bunting":true},
{"title":"Good Friday","date":"2013-03-29","notes":"","bunting":false},
{"title":"
The file is much longer, but it is one long line of text.
I would like to display what bank holiday it is after a certain date, and also if it involves bunting.
I've tried grep and sed but I can't figure it out.
I'd like something like this:
[command] between [date] and [}] display [title] and [bunting]/[no bunting]
[title] should be just "Christmas Day" or something else
Forgot to mention:
I would like to achieve this in bash shell, either from the prompt or from a short bit of code.
You should use a proper JSON parser in a decent programming language, then you can do a lot of work in a safe way without too much code. How about this little Python code:
#!/usr/bin/env python
import json
with open('my.json') as jsonFile:
holidays = json.load(jsonFile)
for holiday in holidays:
if holiday['date'] > '2012-05-06':
print holiday['date'], ':', holiday['title'], \
("bunting" if holiday['bunting'] else "no bunting")
break # in case you only want one line of output
I could not figure out what exactly the output should be; if you can be more specific, I can adjust my example.
You can try this with awk:
awk -F"}," '{for(i=1;i<=NF;i++){print $i}}' file.json | awk -F"\"[:,]\"?" '$4>"2013-01-01"{printf "%s:%s:%s\n" ,$2,$4,$8}'
Seeing that the json file is one long string we first split this line into multiple json records on },. Then each individual record is split on a combination of ":, characters with an optional closing ". We then only output the line if its after a certain date.
This will find all records after Jan 1 2013.
EDIT:
The 2nd awk splits each individual json record into key-value pairs using a sub-string starting with ", followed by either a : or ,, and an optional ending ".
So in your example it will split on either ",", ":" or ":.
All odd fields are keys, and all even fields are values (hence $4 being the date in your example). We then check if $4(date) is after 2013-01-01.
I noticed i made a mistake on the optional " (should be followed by ? instead of *) in the split which i have now corrected and i also used printf function to display the values.
