[R] The program can't stop when searches over all files under folders and subfolders

[Jim Lemon]

Hi John,
If the program is still running, I can only guess that the function is
not exiting properly. If this happened to me, I would run "top" in a
terminal window and see if that process number was actually doing
anything or had gone zombie.
