I am just in the middle of a conversation on the tex list but just in case you are about to post anything to your web site here is a slight simplification. It consists of updating the MiKTeX file database using initexmf instead of the GUI so you don't have to move back and forth during the instructions. The discussion there might correct or improve this further. Regards. --- 1. Create a new tex subfolder of your \localtexmf folder: md \localtexmf\tex 2. Copy your R .sty and .fd files into it, update the MiKTeX texmf file name database and check that Rd.sty is found in the correct place, viz. \localtexmf\tex: cd \Program Files\R\rw2001\share\texmf copy *.* \localtexmf\tex initexmf -u findtexmf Rd.sty #2 should be repeated each time one installs a new version of R or any time the *.sty or *.fd files are changed. (Actually nothing needs to be done if the .sty and .fd files have not changed from one version of R to another and the initexmf command does not need to be run unless the filenames themselves have changed even if their contents have; however, none of these steps will hurt and its safest to do them all.)
