Using install.package('XML') command produces this error:

trying URL

Content type 'application/zip' length 4288136 bytes (4.1 Mb)

Error in read.dcf(file.path(pkgname, "DESCRIPTION"), c("Package", "Type")) :

In addition: Warning messages:

3: In read.dcf(file.path(pkgname, "DESCRIPTION"), c("Package", "Type")) :

file or directory'


Upon receiving this error, I downloaded XML_3.98-1.1.zip directly from cran
site. But this zip file is not a valid archive (cannot open using winzip).
Also trying to install using this downloaded file produces the following
error:

Installing package into 'C:/Users/APandya/Documents/R/win-library/3.0'
(as 'lib' is unspecified)
Warning in install.packages :
  error 1 in extracting from zip file
Warning in install.packages :
  cannot open compressed file 'XML/DESCRIPTION', probable reason 'No such
file or directory'
Error in install.packages : cannot open the connection

I  downloaded this zip file from multiple sources and tried to install with
same result.
