[R] Generating Data Sets -- Each with a Different Name

[Spencer Graves]

      Have you considered using "paste(..., sep="") to generate either 
the object names or file names you want? 

      If you want objects in R, have you considered "assign"?  If you 
want files, then have you considered "write"? 

      hope this helps.
