There are the letters and LETTERS vectors.  For example,

 [1] "a" "b" "c"

I don't think there's any function that does general ASCII
conversions, but you could fairly easily enter your own vector of
characters if letters aren't sufficient.  I imagine you'll have a hard
time entering a null character.  If you're on some platforms, you
could write your own general typecasting function using a fifo, but
those aren't supported everywhere.
