rmarkdown::render to compile LaTeX documents
This example LaTeX file compiles just fine for me using Rstudio, TexShop, and pdflatex example.tex . But rmarkdown::render does not work.
> rmarkdown::render("example.tex", output_format = "pdf_document")
/usr/local/bin/pandoc +RTS -K512m -RTS example.utf8.md --to latex --from markdown+autolink_bare_uris+ascii_identifiers+tex_math_single_backslash --output example.pdf --template /Library/Frameworks/R.framework/Versions/3.3/Resources/library/rmarkdown/rmd/latex/default.tex --highlight-style tango --latex-engine /Library/TeX/texbin/pdflatex --variable graphics=yes --variable 'geometry:margin=1in'
! LaTeX Error: Can be used only in preamble.
See the LaTeX manual or LaTeX Companion for explanation.

Never mind. tools::texi2pdf("example.tex") worked for me with Rstudio and R from the command line. The R GUI failed in error, though.
