[R] filtering values

I was wondering if there is a simple way to filter out a bunch of
specific vales from a vector (eg zero).

Also, is there a way to create a null vector?  What I mean by this is
that if I declare a vector vector <- NA, it is a vector with [NA].  I
want an empty vector, so that I can append to it later.
