High-level functions to render 'LaTeX' fragments in plots, including as labels and data symbols in 'ggplot2' plots, plus low-level functions to author 'LaTeX' fragments (to produce 'LaTeX' documents), typeset 'LaTeX' documents (to produce 'DVI' files), read 'DVI' files (to produce "DVI" objects), and render "DVI" objects.
The default 'TeX' typesetting engine is taken from
getOption("xdvir.engine") (currently one of
"luatex" or "xetex").
Whether to use a DVI cache is taken from
getOption("xdvir.useDVIcache").
This is TRUE by default, but setting it to FALSE
will ensure that typesetting will always occur (even if the
'LaTeX' fragment has been typeset before).
Whether to substitute very thin 'TeX' rules (lines) with
line segments (rather than rectangles) is taken from
getOption("xdvir.substituteRule").
This is NULL by default, which is taken as TRUE
(i.e., DO substitute), but can be set to FALSE
to force all rules to be drawn as rectangles.
