I am currently designing my RStudio – Dropbox – Mardown/Knitter/Wordpress – Github workflow. One problem is that working on multiple machines with different version of Windows means I somehow need to tell R where my Dropbox folder is located.

I used to set the working directory at the beginning of my R scripts but it became tedious to change the path all the time. The solution might be to add definition of ‘dropbox.folder.path’ variable to .Rprofile files. Or there is a hard way – to write a script detecting Dropbox location automatically.

I have found this hint and created the script below. It is for Windows only (because I do not have Dropbox on the cluster). However, it should be easy to modify it for linux / MacOS if needed (see this shell script).
