is there any RStudio Addin to compare two files (.R or .Rmd)? I tried
addinslist by Dean Attali, but I couldn't find anything. I know I could just build a GitHub repo and then use the Version Control feature to access Git file diff. But the point is, sometime I don't want to compare two different versions of the same file: I may just want to compare two different .Rmd files, because I want to see how the initial options differ among them (for example).
Also, while I do use version control for any serious project, sometimes I just want to have a little fun with R without the need to build a Git repo I would welcome a feature which allows me to diff .R/.Rmd files independently from version control.
