Hi,

I hope I haven't got this wrong, but I don't think one needs Perl 
installed if they install the "precompiled" packages for Windows right?

I'm just wondering if the first sentence in the "R Installation and 
Administration" can be re-worded a bit so newbies won't get confused....

Ah I see the confusion.  I am taking it you are reading the "R 
Installation and Administration", Section 5.1.  It says "Installing source 
packages requires that Perl 5.004 or later be installed."  Note the 
keywords "source packages".  It means if you want to download the "source 
codes" of the package(s), i.e. a tarball file, and compile the package 
yourself, then you will need Perl.

Most, if not all, packages on CRAN have a "pre-compiled" windows version, 
i.e. a ZIP file.  That is why the easiest way is to install under Rgui, as 
the default URL setting in Rgui is to look under the appropriate directory 
in which pre-compiled package files located.

An alternative is to download the precompiled zip file and unzip them into 
your R library folder.
