R devel - Dec 2012 - Scanning a R script for potentially insidious commands

Hey all,

We are building a R connector for our web application.
The user can upload a script so it can be executed on the server.

Is there a way to scan the script for insidious commands (writing on the
disk for example) and purge them out?
I guess a simple search is not enough so is there a way to analyse the
pseudo code?

Best,

Etienne

Completely, not that I know of: but grepping for system() and eval() should
catch a majority of red flags.
