Dear list,

I was trying to install biomaRt package.
>  biocLite('biomaRt')

Everything worked, but I had this warning:

Warning: unable to move temporary installation 'C:\Program Files\R\R-2.15.0\library\file77847d9453b\XML' to 'C:\Program Files\R\R-2.15.0\library\XML'

However,:
package 'biomaRt' successfully unpacked and MD5 sums checked

Then, when I was trying to load the library I had the following error:
>  library(biomaRt)
Error in loadNamespace(i, c(lib.loc, .libPaths())) :
  there is no package called 'XML'
Error: package/namespace load failed for 'biomaRt'

Enigmatically, there is no such directory 'file77847d9453b' in 'C:\Program Files\R\R-2.15.0\library'
I would appreciate an advise how to fix this error!

Best regards
Galina
