Spoiler: I wanted to post this question and then decided to give it a shot myself. (It is a bit weird asking a question and answering it yourself, but when i read this i felt motivated enough :) https://stackoverflow.com/help/self-answer)
So far i got a workaround via python (see answer below), but it works and saved me quite some silly work. So i decided i might not be the only one googling that question and share my result.
回答1:
As i spoilered in the question i found a workaround. It still requires improvement as it uses Python in the backend, so any suggestions for a R only integration are welcome. (Maybe the python part is written in C and can be also wrapped in R).
I wrote a little RStudio addin and shared it here: https://github.com/Timag/imageclipr.
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/.
