I am running R 2.14.1 on a Windows XP (32 bit) system, and am trying to

dual-core laptop). Rmpi appears to install OK (see below), but I am
encountering the following error when I try and load the package:
utils:::menuInstallLocal()

Error in library(Rmpi) :
package 'Rmpi' does not have a NAMESPACE and should be re-installed
That mean you have not installed a binary package that has been built
for R-2.14.x for Windows, but something else, probably for a much older
version. You need more recent version (e.g. by trying to install it from
sources yourself).

I have attempted to re-install Rmpi several times without success (both Rmpi
0.5-9 and 0.6-0 from local ZIP files). As suggested on the developer
website for Rmpi (http://www.stats.uwo.ca/faculty/yu/Rmpi/) I am using
MPICH2 as my MPI implementation and I have followed the 'Rmpi for Windows'
installation instructions detailed there, and MPICH2 appears to be running
properly.
Does anyone have an insight into the nature/cause of the namespace issue and
how I can resolve it? I will be most grateful!
Many thanks,
Tom
