I am currently working on a joint project, with all the files stored in a Dropbox. To avoid changing the working directory every time we change something, we use the following code:
this.dir = dirname(parent.frame(2)$ofile)
setwd(this.dir)
This is working fine when sourcing the code in Rstudio, but we are looking for a solution that is working outside RStudio.
The team is working on Mac and Windows.
