Looks like you have some network problem and cannot access the repositories. Ask you local administrator for help.


  >*install.packages( "c:/program files/R/XML_2.6-0.tar.gz", type="source",
repos=NULL)*
*Error  :-*  'sh' is not recognized as an internal or external command,
operable program or batch file.


It is not straightforward nor very easy to install XML from sources.
You'd need a) the tools for compiling packages from source and even then you'd need b) to have additional software such as the XML sources and need to adapt some files in the XML package.
