Simple wrapper function that either calls Sweave
for Rnw exercises or knit for Rmd exercises.
xweave(file, quiet = TRUE, encoding = "UTF-8", engine = NULL, envir = new.env(),
pdf = TRUE, png = FALSE, svg = FALSE, height = 6, width = 6, resolution = 100,
highlight = FALSE, ...)
character, ignored. The encoding is always assumed to be UTF-8.
character indicating whether "Sweave" (default) or
"knitr" should be used for rendering Rnw exercises.
argument passed to knit. By default,
or if envir = NULL a new.env() is created for each
xweave() call.
arguments passed to
Sweave or opts_chunk, respectively.
In the latter case: pdf/png/svg are mapped to dev;
height/width are mapped to fig.height/fig.width;
and resolution is mapped to dpi. highlight is ignored for
Sweave.
Depending on whether file has an .Rnw or .Rmd suffix,
either Sweave or knit is called for
weaving the file by default. Rnw exercises can optionally also be weaved by
knit by setting engine = "knitr".
If png = TRUE or svg = TRUE when calling Sweave, then
the resulting includegraphics statements are supplemented with the .png
or .svg suffix of the corresponding graphics. For svg a simple
graphics device hook .xweave_svg_grdevice is provided on-the-fly
for plug-in into Sweave.
