You don't give details, so the explanation is uncertain, but the answer is clear: don't do that.

If you are trying to install a binary build, don't do that. It might appear to work but fail in messy ways if you use it in the wrong version of R. Some packages link to R internals, and those might have changed.

If you are trying to install from source, but the author said you need a particular version of R, then you could modify the DESCRIPTION file: but presumably the author had a reason to ask for a particular version, so don't do that either.
