Utilities for Processing Rd Files


Utilities for converting files in R documentation (Rd) format to other formats or create indices from them, and for converting documentation in other formats to Rd format.





the path to a file to be processed.


a list of file names specifying the R documentation sources to use, by either giving the paths to the files, or the path to a directory with the sources of a package.


further options to control the processing, or for obtaining information about usage and version of the utility.


R CMD Rdconv converts Rd format to plain text, HTML or LaTeX formats: it can also extract the examples.

R CMD Rd2pdf is the user-level program for producing PDF output from Rd sources. It will make use of the environment variables R_PAPERSIZE (set by R CMD, with a default set when R was installed: values for R_PAPERSIZE are a4, letter, legal and executive) and R_PDFVIEWER (the PDF previewer). Also, RD2PDF_INPUTENC can be set to inputenx to make use of the LaTeX package of that name rather than inputenc: this might be needed for better support of the UTF-8 encoding.

R CMD Rd2pdf calls tools::texi2pdf to produce its PDF file: see its help for the possibilities for the texi2dvi command which that function uses (and which can be overridden by setting environment variable R_TEXI2DVICMD).
