Charles,
masked(), find() and remove() will help you sort things out.
Be careful which function you actually delete!
# e.g.
#> masked()
#[1] ".Last.value" ".Random.seed" "last.dump"
#> find("last.dump", num=T)
# D:\apps\stats\splus70\users\THOMPS~1 Scripts
# 1 2
#> remove(c("last.dump"), where=2)
#> masked()
#[1] ".Last.value" ".Random.seed"
