##### 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. Name of 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. Ignored if emulation (see the texi2dvi argument) is used.
texi2dvi
character (or NULL). Script or program used to compile a TeX file to dvi or PDF, respectively. The default (selected by "" or NULL) is to look for an executable on the path and otherwise emulate the script with system calls.
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. 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 texinputs, then ‘R_HOME/share/texmf’ and finally the default path. Analogous changes are made to BIBINPUTS and BSTINPUTS settings.

MiKTeX has a texi2dvi executable 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 on OS X) 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.x and texify), option --max-iterations=20 is used to avoid infinite retries.
