The version of Rd.sty in R_HOME/share/texmf uses url.sty. This isnormally installed, and can be obtained from any CTAN node or mirror:see http://www.tug.org/ctan.htmlIt also uses the standard package bm, which is part of the standardtools bundle and should be part of any reasonably recent LaTeXinstallation.The reference manual is made using the ae fonts package. If you do nothave that available, you can get it from CTAN, or set the environmentvariable R_RD4DVI to "", but the latin1 characters in text.Rd (and afew other places) will be missing. Other alternatives are discussedin the R-admin manual.To make PDF versions of the manuals you will need pdf(la)tex and thehyperref package. If you want to avoid making the hyperlinks, you canset the environment variable R_RD4PDF to "times" (or even to "").You may have to increase the poolsize of your pdflatex to process thereference manual with hyperlinks, although these days the limits areset high.pdftex will warn (correctly) about missing hyperlinks in formingrefman.pdf.
