[R] Where is gdata?

[Spencer Graves]

Hi, Stephen:


       The directory "C:\Users\satimiswin764\My 
Documents\R\win-library\2.12\gdata\perl" is NOT the perl interpreter but 
only perl code in the gdata package for R, invoked by certain R 
commands.  You need to install something like "Strawberry perl", as I've 
previously stated.
