[R] Help with installing a .tar.gz package on windows

[Lucy Leigh]

Hi, 
I have a source package that isn't available as a windows zip file. Can
anyone explain to me how I can install this on my windows R platform?
When I use the following code: 
 install.packages("PReMiuM_3.0.21.tar.gz", type = "source") 


I get this error message: 



* installing *source* package 'PReMiuM' ... 
** libs 

*** arch - i386 
ERROR: compilation failed for package 'PReMiuM' 
* removing 'C:/Program Files/R/R-3.0.1/library/PReMiuM'

Thanks for any help anyone can give me, 
Lucy
