Search on either the R_SIG-MAC list or in Google for "show dotted  
files". Apply that method to your working directory, delete the  
invisible .RData file, and then decide whether you want to revert to  
the default Finder behavior.

I have globally changed my system to show dotted files, but not  
everyone feels safe doing so.

At the terminal window I have entered:

defaults write com.apple.Finder AppleShowAllFiles YES

  ..... and then <pt>-click-hold> on Dock-Finder-icon, choose relaunch

Or you could open a Terminal window which will by default open in / 
Users/ctu/ and type:

  rm .RData
