There's at least one typo below, but besides that, it's hard to tell. Do the directories you're trying to set exist? More inline.

I don't think the terminal semicolon is needed, though it shouldn't cause a problem.

Does C:/PROGRA~1/R/win-library exist? Does C:/PROGRA~1/R/win-library/2.5 exist? Does normalizePath("C:/PROGRA~1/R/win-library", winslash="/") give a directory that exists?

These lines have the typo: it should be C:/PROGRA~1, not C:PROGRA~1.
