Creating an R package for windows

I created an R package on Linux (and it is working on Linux), but I can't make the same package work on Windows.

What I tried to do (maybe it was a bit foolish) was to convert the tar.gz into a Zip file and to install it fr开发者_C百科om the R GUI.

However, when I load the package library("myPackage") then I get the following message:

  Error in library("myPackage") :
     there is no package called 'myPackage'

Should I try to build the package directly from Windows with the R tools?

To build an R package on Windows, download the tools at
     http://cran.r-project.org/bin/windows/Rtools/
and follow the instructions at

Yes, you should make it directly on Windows. See the R Extensions manual and a number of tutorials on the web.
