R: Forcing Plotly to Save "Full Sized" Plots? - html

Question

I am working with the R programming language. I am following the tutorial here :
I was able to make the following plot:
library(dplyr)
library(plotly)
data <- read.csv("https://raw.githubusercontent.com/plotly/datasets/master/gapminderDataFiveYear.csv")
data_2007 <- data[which(data$year == 2007),]
data_2007 <- data_2007[order(data_2007$continent, data_2007$country),]
slope <- 2.666051223553066e-05
data_2007$size <- sqrt(data_2007$pop * slope)
colors <- c('#4AC6B7', '#1972A4', '#965F8A', '#FF7070', '#C61951')
fig <- plot_ly(data_2007, x = ~gdpPercap, y = ~lifeExp, color = ~continent, size = ~size, colors = colors,
type = 'scatter', mode = 'markers', sizes = c(min(data_2007$size), max(data_2007$size)),
marker = list(symbol = 'circle', sizemode = 'diameter',
line = list(width = 2, color = '#FFFFFF')),
text = ~paste('Country:', country, '<br>Life Expectancy:', lifeExp, '<br>GDP:', gdpPercap,
'<br>Pop.:', pop))
fig <- fig %>% layout(title = 'Life Expectancy v. Per Capita GDP, 2007',
xaxis = list(title = 'GDP per capita (2000 dollars)',
gridcolor = 'rgb(255, 255, 255)',
range = c(2.003297660701705, 5.191505530708712),
type = 'log',
zerolinewidth = 1,
ticklen = 5,
gridwidth = 2),
yaxis = list(title = 'Life Expectancy (years)',
gridcolor = 'rgb(255, 255, 255)',
range = c(36.12621671352166, 91.72921793264332),
zerolinewidth = 1,
ticklen = 5,
gridwith = 2),
paper_bgcolor = 'rgb(243, 243, 243)',
plot_bgcolor = 'rgb(243, 243, 243)')
Then, I tried saving the file:
htmltools::save_html(html = fig, file = "file.html")
The problem is, that this plot is saving in a "stretched" format:
Is there any way that I can "force" R/plotly to save a "full sized" plot instead of this "stretched" version?
Thanks!

You could specify the width and height in plot_ly like this:
library(dplyr)
library(plotly)
data <- read.csv("https://raw.githubusercontent.com/plotly/datasets/master/gapminderDataFiveYear.csv")
data_2007 <- data[which(data$year == 2007),]
data_2007 <- data_2007[order(data_2007$continent, data_2007$country),]
slope <- 2.666051223553066e-05
data_2007$size <- sqrt(data_2007$pop * slope)
colors <- c('#4AC6B7', '#1972A4', '#965F8A', '#FF7070', '#C61951')
fig <- plot_ly(data_2007, x = ~gdpPercap, y = ~lifeExp, color = ~continent, size = ~size, colors = colors,
type = 'scatter', mode = 'markers', sizes = c(min(data_2007$size), max(data_2007$size)),
marker = list(symbol = 'circle', sizemode = 'diameter',
line = list(width = 2, color = '#FFFFFF')),
text = ~paste('Country:', country, '<br>Life Expectancy:', lifeExp, '<br>GDP:', gdpPercap,
'<br>Pop.:', pop),
autosize = F, width = 1200, height = 600)
fig <- fig %>% layout(title = 'Life Expectancy v. Per Capita GDP, 2007',
xaxis = list(title = 'GDP per capita (2000 dollars)',
gridcolor = 'rgb(255, 255, 255)',
range = c(2.003297660701705, 5.191505530708712),
type = 'log',
zerolinewidth = 1,
ticklen = 5,
gridwidth = 2),
yaxis = list(title = 'Life Expectancy (years)',
gridcolor = 'rgb(255, 255, 255)',
range = c(36.12621671352166, 91.72921793264332),
zerolinewidth = 1,
ticklen = 5,
gridwith = 2),
paper_bgcolor = 'rgb(243, 243, 243)',
plot_bgcolor = 'rgb(243, 243, 243)')
htmltools::save_html(html = fig, file = "file.html")

Output:
You can change the size to whatever you want.
