In `older' versions of R on Windows, detach()ing a package that contains dll does not unload (or at least unlock) the dll. I have not tried the current version. It's much safer to quit _all_ instances of R, restart, and re-install the packages. Pre-compiled packages for Windows can be installed in sort of four ways: 1. The Rgui menu 2. install.packages() from the R prompt 3. Download the zip file and unpack in the desired directory 4. Download the zip file and use install.packages(..., CRAN=NULL) For #3 above, link.html.help() should be run at the R prompt post-unzip.
