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? > On 28/05/2015 07:38, Prof Brian Ripley wrote: >> This really should have been sent to the package maintainer. Yes, I actually sent an email to the package maintainer on May 21 but figured I would try the R help forum as well.
