Compile LaTeX Files

Run latex/pdflatex, makeindex and bibtex until all cross-references are resolved to create a dvi or a PDF file.

Usage
texi2dvi(file, pdf = FALSE, clean = FALSE, quiet = TRUE,
texi2dvi = getOption("texi2dvi"),
texinputs = NULL, index = TRUE)texi2pdf(file, clean = FALSE, quiet = TRUE,
texi2dvi = getOption("texi2dvi"),
texinputs = NULL, index = TRUE)
Arguments
file

character string. Name of the LaTeX source file.

pdf

logical. If TRUE, a PDF file is produced instead of the default dvi file (texi2dvi command line option --pdf).

clean

logical. If TRUE, all auxiliary files created during the conversion are removed.

quiet

logical. No output unless an error occurs.

texi2dvi

character string (or NULL). Script or program used to compile a TeX file to dvi or PDF. The default (selected by "" or "texi2dvi" or NULL) is to look for a program or script named texi2dvi on the path and otherwise emulate the script with system2 calls (which can be selected by the value "emulation"). See also ‘Details’.

texinputs

NULL or a character vector of paths to add to the LaTeX and bibtex input search paths.

index

logical: should indices be prepared?

Details

texi2pdf is a wrapper for the common case of texi2dvi(pdf = TRUE).

Despite the name, this is used in R to compile LaTeX files, specifically those generated from vignettes and by the Rd2pdf script (used for package reference manuals). It ensures that the R_HOME/share/texmf directory is in the TEXINPUTS path, so R style files such as Sweave and Rd will be found. The TeX search path used is first the existing TEXINPUTS setting (or the current directory if unset), then elements of argument texinputs, then R_HOME/share/texmf and finally the default path. Analogous changes are made to BIBINPUTS and BSTINPUTS settings.

The default option for texi2dvi is set from environment variable R_TEXI2DVICMD, and the default for that is set from environment variable TEXI2DVI or if that is unset, from a value chosen when R is configured.

A shell script texi2dvi is part of GNU's texinfo. Several issues have been seen with released versions, so if yours does not work correctly try R_TEXI2DVICMD=emulation.

On Windows the option "texi2dvi" is normally unset. The MiKTeX command texify.exe is a suitable choice for texi2dvi, and is tried as from R 3.2.3 if the argument is blank or NULL and a program or script texi2dvi is not found.

MiKTeX had a texi2dvi executable until Sept 2015, but no other Windows TeX installation that we know of does, so emulation is used on e.g.TeXLive installations on Windows.

Occasionally indices contain special characters which cause indexing to fail (particularly when using the hyperref LaTeX package) even on valid input. The argument index = FALSE is provided to allow package manuals to be made when this happens: it uses emulation.

Value

Invisible NULL. Used for the side effect of creating a dvi or PDF file in the current working directory (and maybe other files, especially if clean = FALSE).

Note

There are various versions of the texi2dvi script on Unix-alikes and quite a number of bugs have been seen, some of which this R wrapper works around.

One that was present with texi2dvi version 4.8 (as supplied by macOS) is that it will not work correctly for paths which contain spaces, nor if the absolute path to a file would contain spaces.

The three possible approaches all have their quirks. For example the Unix-alike texi2dvi script removes ancillary files that already exist but the other two approaches do not (and may get confused by such files).

Where supported (texi2dvi 5.0 and later; texify.exe from MiKTeX), option --max-iterations=20 is used to avoid infinite retries.

The emulation mode supports quiet = TRUE from R 3.2.3 only. Currently clean = TRUE only cleans up in this mode if the conversion was successful---this gives users a chance to examine log files in the event of error.

All the approaches should respect the values of environment variables LATEX, PDFLATEX, MAKEINDEX and BIBTEX for the full paths to the corresponding commands.
