[R] Generating EPS figures automatically (like Sweave)

[eariasca]

Hello,

Is there a way to generate EPS figures automatically out of a chunk  
of code?  Basically, I would like to do something like Sweave does (I  
just find it a little cumbersome to create a .Rnw file and then keep  
track of the figure numbering).  Thanks for your time.
