[NTG-context] Difficulties using the r module

I spotted the announcement of the use of R in ConTeXt and was quite interested in trying it out. However, so far I haven't been able to get it to work. It appears that R is not being called by texexec and the .tmp.out are not being found, despite the fact that they are being produced. Are there more details on installing and using this module? I think it would be quite useful. Thanks for any advice, Matt Some details are that I am using Mac OS X 10.4.7, R-2.3.1, and ConTeXt ver: 2006.06.28 from gwTeX and running the sample file contained in m-r.tex. I have also tried using context live @ contextgarden.net with the same results as on my personal machine. Here is some output from the log file: system : module r loaded (/usr/local/teTeX/share/texmf.local/tex/context/base/m-r.tex) ... systems : begin file r at line 11 (/usr/local/teTeX/share/texmf.local/tex/context/base/pdfr-ec.tex) verbatim : file r-r-1.tmp.out does not exist verbatim : file r-r-2.tmp.out does not exist verbatim : file r-r-4.tmp.out does not exist verbatim : file r-r-5.tmp.out does not exist (./r-r.tmp figures : figure ushape can not be found floatblocks : 1 placed ) verbatim : file r-r-6.tmp.out does not exist (./r-r.tmp figures : figure lattice can not be found floatblocks : 2 placed ) verbatim : file r-r-7.tmp.out does not exist ...
