deleting objects from sim environment

[Steve Cumming]

Sometimes, large objects like rasters are loaded, processed, and then no longer needed. To save memory, I'd like to delete them once the module has done with them.

I tried 

rm(largeRaster,envir=sim)

but that does not work. Suggestions?

rm(largeRaster,envir=envir(sim))

The sim is not an environment; it is a simList. To get the environment of the simList where all the objects are stored, use the envir( ) accessor.
