  verbose = FALSE,
  purl = TRUE,
  tangle = purl,

)

...

Arguments that will be passed to rmarkdown::render and rmarkdown::pdf_document. Our defaults set a LaTeX template, toc = TRUE, and the pandoc_args includes use of the listings class. Users may override by specifying named arguments for render(): c("output_file", "output_dir", "output_options", "intermediates_dir", "knit_root_dir", "runtime", "clean", "params", "knit_meta", "envir", "run_pandoc", "quiet", "encoding"). Users may also specify named arguments for pdf_document: ("toc", "toc_depth", "number_sections", "fig_width", "fig_height", "fig_crop", "fig_caption", "dev", "df_print", "highlight", "template", "keep_tex", "latex_engine", "citation_package", "includes", "md_extensions", "pandoc_args", "extra_dependencies").

verbose

The opposite of render(quiet = TRUE). Shows compile commentary and pandoc command. Can be informative!

purl

Default TRUE

tangle

Default TRUE, synonym for purl

backup

Default TRUE. Will create backup copies of pdf, R, Rnw files before replacing them. Uses kutils::file.backup

Examples

tdir <- tempdir()
fmt <- "rmd2pdf-guide"
dirout <- initWriteup(fmt, dir = file.path(tdir, fmt))
print(dirout)
list.files(dirout)
# \donttest{
of1 <- try(rmd2pdf("skeleton.Rmd", wd = dirout))
if(inherits(of1, "try-error")){
    MESSG <- paste("Compiling the markdown file failed, perhaps",
                  "you should run with parameters verbose=TRUE",
                  "and keep_tex=TRUE")
    print(MESSG)
} else {
    ## Check the result file:
    MESSG <- paste("Check the directory", dirout, "for results.")
    print(MESSG)
    list.files(dirout)
    if(interactive() && file.exists(file.path(dirout, "skeleton.pdf"))) {
        browseURL(of1)
    }
}
# }
unlink(dirout)
