If in the console you enter the command:

path

then it will display a semicolon separated list of folders.  You want the folder
that contains the tools to be at the beginning so that you eliminate
the possibility
of finding a different program of the same name first in a folder that comes
prior to the one where the tools are stored.

I was assuming that MyRPackages and R are on the same disk.  If they are not
then you need to specify the disk too.  That is if MyRPackages is on C and R
is installed on D then install your package via:

d:
cd \Program Files\R\rw2010
bin\R CMD install c:/MyRPackages/example

Note that bin\R means to run R.exe in the bin subfolder of the current folder 
using command script install and the indicated source package.

If you are not sure where R is installed then enter the following at the Windows
console prompt to find out (this will work provided you let it install the key
into the registry when you installed R initially).  The reg command is a command
built into Windows (I used XP but I assume its the same on other versions)
that will query the Windows registry:

reg query hklm\software\r-core\r /v InstallPath

Sorry, there is an error in the above.  It should be:

bin\R CMD install c:/MyRPackages/example

or 

bin\Rcmd install c:/MyRPackages/example

Also try googling for

  making creating R packages

and you will find some privately written tutorials on all this.
