There have been a lot of changes recently in R-devel, so I've been uploading frequent Windows builds to CRAN. I'm heading out to a conference this week, so it's unlikely there will be any more builds until Jan 18 or later. (I've just done one today; it may not show up until tomorrow). If you were unaware of these builds, they are available at your favourite CRAN mirror (list here: http://cran.r-project.org/mirrors.html) in the bin/windows/base directory. Follow the link to "the r-devel release" or the "r-patched release". Duncan Murdoch
