[R] Windows 7 installation of .qz package from SourceForge

[Prew, Paul]

Thank you Duncan,  the 2nd instructions worked. The both probably would have worked, but I had some code (below) that threw an error.  It's designed to automatically set the internet connection to my Windows setting, so R would know the proxy server used at my worksite.  I had seen this suggestion in the archives of R-Help.  However, this code in the R-2.14.0/etc./Rprofile.site file wasn't being recognized as a valid command, so I commented it out (the code works fine when I run it in the RGUI).  Thanks again, Paul

# use the proxy settings for Windows/IE:
setInternet2(TRUE)

There's no .zip extension, but R seems to go to work on the installation with a couple warning messages and one error.

tar.gz files are source packages.  .zip is a binary image of an 
installed package.

To install a tar.gz, you can't use the menu items.  If you have the 
necessary tools set up properly, it should work to do

install.packages(".../path/to/metRology_0.9-06.tar.gz", type="source", 
repos=NULL)

from within R.

If that fails (as it likely will if the package has C or Fortran code 
and you haven't installed the right compilers), you need to get the R 
tools from <CRAN mirror>/bin/windows/Rtools.

You can also install from outside R using "R CMD INSTALL 
.../path/to/metRology_0.9-06.tar.gz".
