Hi All:

When I ask about updating packages in my R distribution,  it lists ggplot2 version 3.0.0 as being available.  I know that ggplot2 version 3.0.0 has made some significant changes that will break certain things.  I would like to install the new version, to see if it breaks anything that I do,  but I would also like to be able to revert back to the old version if it makes it impossible to do some of the work I need to get done,  and then switch back again to the new version to test some more.  Is there some elegant way of doing this?  If I just drag the appropriate Folder out of my directory and replace it with the one I want,  will that do it,  or are there too many other dependencies that are involved?

Thanks for any suggestions.
