You can't just call makePDpackage() with no arguments. You have to 
explicitly tell the function what files to use to make your package 
because it can't just figure it out on its own.

If you type ?makePDpackage at an R prompt it will show you information 
about this function.

However, simply making the package is only half the battle. You will 
also need to install it, which is not a simple task for someone without 
computer knowledge. You will probably need to find someone local who 
does have computer knowledge to help you get set up to install packages, 
and possibly install it for you. Information on how to do so can be 
found in the R FAQ for windows under section 4.1.

Best,

Jim
