Answer 1

I wrote a little RStudio addin and shared it here: https://github.com/Timag/imageclipr. Edit: It works now without Python across plattforms (Mac, Windows, Linux), thanks to great contributions.

Walkthrough:

Basically i started here: How do I read a jpg or png from the windows clipboard in python and vice versa?.

I use this code to save the image:

from PIL import ImageGrab
im = ImageGrab.grabclipboard()
im.save('somefile.png','PNG')

Then i wrote a wrapper with library(reticulate) to run the python code from R. Thats what covers the "right part" of the gif: To copy the image to a directory.

For the "left part" I use library(rstudioapi). I take the current

• file: getActiveDocumentContext()$id
• line: getActiveDocumentContext()$selection[[1]]$range$start
• directory: getActiveDocumentContext()$path

And then wrote a small RStudio addin: https://rstudio.github.io/rstudioaddins/.
