Is there anyway to change the color schemes for Rstudio? It comes with 6 or 7 default, pre-packaged
Unfortunately there's not currently a way to do this. RStudio's themes are based on themes for the ACE text editor, which it embeds. It can generate internal themes based on ACE themes, so if you have an ACE theme you'd really like to use with RStudio, you can submit a pull request to RStudio (which is hosted on GitHub) for consideration.
