It would be possible to call other R scripts using calls to ?system or 
?system2 and ?Rscript, provided you formatted what you passed as [args] 
and how your scripts handled [args].

[R] external R scripts
Sent by:
r-help-bounces at r-project.org

Is it possible to send data from an executing R script, to external R 
script files, on linux in this case, get that external R script to 
execute, and pass results back to the central script?  If so what commands 
should I be looking at?  I've googled for R and external, stuff like that 
but no luck.

The reason for the question is that I need to generate simulation data, 
then perform several different analyses on the same data set, then collate 
the results.  All individual analyses can be done sequentially, or perhaps 
more quickly by doing the individual analyses simultaneously if I pass 
them to external functions.
