Thanks a bunch; I suspect something similar to the Sophos Anti-Virus
detection is happening at my workplace that results in the XML package being
blocked.  I am one step removed from the installation process there (also
the reason why I am working with R version 3.1.2) -- the frustrating thing
is that I am able to download and get everything working correctly at home.
Knowing that your IT folks had to bypass the anti-virus software to get it
installed gives me some additional info. to try to resolve this issue.  I am
wondering if the package maintainer or others might be able to modify
dtd.zip?

Yes, I actually sent an email to the package maintainer on May 21 but
figured I would try the R help forum as well.
