I concur with Rolf.
.RData files (the ones with nothing before the period) are just traps for your
future self, with no documentation. I avoid them like the plague. I refer to
specifically-named Something.RData files in my .R/.Rnw/.Rmd files to cache
results of long computations, but they are optional in my workflow because I
always have R code that can regenerate them.
.Rprofile files offer consistency of behavior regardless of which working
directory you use, and you can comment them.
