I think at least one OS will require that you also include type="source" and I would advise including dependencies=TRUE.

Generally one does not need to unzip source versions of packages unless you want to look at the contents separately. With Windoze and Macs you need to specify type="source" [unless getOption("pkgType") is set to that value] and may need to have the appropriate system tools. You did not show your exact call to install.packages().

The problem description doesn't allow a definite answer. If problems persist, then you should post more complete descriptions of your methods, your OS and R versions.
