[R] ifelse, evaluating to given number

I would like to take advantage of the vectorized 'ifelse' command. Given a
filter number of 'filter', if the nm'th value in a n x m matrix I would
like to perform the following.
newMatrix <- ifelse(myMat <=filter, filter+1, "existing nm'th value").
What do I use to express the "existing nm'th value" in this expression if I
want to test an nm th value is less than 'filter', if false use the
existing nm'th value.
This does not seem to be documented in the help().
