Hello,
I have package XML installed on Windows 7, R 3.0.3 and I had no problem at all. Can't you try (it worked with me)

install.packages("XML", repos = "http://cran.dcc.fc.up.pt";)

Hope this helps,

Rui Barradas

I have confirmed with IT that there is no restriction on downloading this
zip file from any of these sources. Also I am getting same error when I try
from my home network as well.

@Uwe I tried the same steps from office as well as home network with same
results. Are you using windows 7 with R 3.0.3?

I have seen same question being asked by others without any resolution. Is
anything special about XML package? I am OK use older version of package
but in archives there are no zip files (only gz files). Is windows
platform
not recommended for R?


Right, and you can try to install these from sources.
But I doubt you need it. You still have not told us if you tried another
mirror to download the XML file from and what you local IT support tells
you while your downloads are incomplete.

  Thank you for response Uwe. I tried multiple times by downloading the

for me in using R. Appreciate any help on this.


Please ask your local IT staff.

I get, using the same mirror:

  options("repos"=c(CRAN="http://watson.nci.nih.gov/cran_mirror";))
install.packages("XML", lib="d:/temp")

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 :

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