I have RStudio and R installed in my SSD with only 13 GB of empty space left. The problem is that when I launch some demanding algorithm with RStudio, it quickly fills my SSD with some temporary files that are quit huge, probable because of 16 GB RAM I have in my computer. However, I also have 1 TB almost empty hard disk in the same computer. Is it possible to reroute those temp files to hard disk? Any suggestions how to do this?
One solution I have tried was to specify alternative values for TMPDIR, TMP and TEMP variables in .Renviron file. However, it did not solved the problem.
IIRC, these environment variables need to be set before R is launched, so setting them in an .Renviron is too late. You can try changing the default Windows environment environment variables for the system rather than setting them in .Renviron.
