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.
