Install the two versions in two different *libraries* and update

For the moment I have two different R installations, each with a different version of lme4. However it would be convenient if I could have the same version within the same R installation such that I can run a code chunk on one lme4 version and immediately after run the same code chunk on another lme4 version. Does anyone know if this is possible?
