Given an arbitrary set of character vectors:

myvect1 <- c("abc","3","4")
myvect2 <- c("2","3","4")

I would like to develop a function that will convert any vectors that can
be PROPERLY converted to a numeric (myvect2) into a numeric, but leaves
character vectors which cannot be converted (myvect1) alone.  Is there any
simple way to do this (e.g. some function that tests if a vector is
coercible to a numeric before doing so)?
