Hot to save html file only from R and htmlwidgets?

Question

I an using R to draw heatmap. Heatmaply and htmlwidget were installed. Fox example i exec following code:

library("htmlwidgets")
library("heatmaply")
heatmaply(mtcars) %>% saveWidget(file="test.html")

This always generate a test.html file and a test_files folder, but i want the test.html only. I try saveWidget(file="test.html",,selfcontained=TRUE). This just place the js library in the test.html, making test.html too big.

If you want a functioning heatmap, you need to save the libraries either in the html file itself or in the library folder. — alan ocallaghan, Sep 29 '17 at 18:07
notice that heatmaply now offers the file argument to save your heatmaply as html or png files. — Tal Galili, Oct 07 '17 at 09:18

Use self-contained=FALSE to create plain HTML and a seperate folder, then use system to remove that folder:

heatmaply(mtcars) %>% 
  saveWidget(file="test.html", selfcontained = FALSE)
system('rm -r test_files')

Just be careful you don't have a folder named x_files, where x is the name of your plot output!

This lost the whole purpose of `selfcontatined` and the library folder and is not a solution. The html may not work if copied to other place. – dracodoc Jan 11 '18 at 15:06

A simpler solution is available in the recent version of heatmaply, simply use:

library("heatmaply")
heatmaply(mtcars, file="test.html")
