I have been creating PDF reports via RMarkdown for a couple of months, but after installing MikTex, R and the rmarkdown and tidyverse packages on a new computer today I received the following error message when connecting to a PDF file:
"C:/PROGRA~2/Pandoc/pandoc" +RTS -K512m -RTS Test.utf8.md --to latex --from markdown+autolink_bare_uris+ascii_identifiers+tex_math_single_backslash --output test.pdf --template "C:\Users\drewm\Documents\R\win-library\3.4\rmarkdown\rmd\latex\default-1.17.0.2.tex" --highlight-style tango --latex-engine xelatex --variable graphics=yes --variable "geometry:margin=1in" ! Undefined control sequence. <argument> \LaTeX3 error: Erroneous variable \c__fontspec_shape_n_n_tl used! l.3806 \emfontdeclare{ \emshape, \eminnershape } pandoc.exe: Error producing PDF Error: pandoc document conversion failed with error 43 In addition: Warning message: running command '"C:/PROGRA~2/Pandoc/pandoc" +RTS -K512m -RTS Test.utf8.md --to latex --from markdown+autolink_bare_uris+ascii_identifiers+tex_math_single_backslash --output test.pdf --template "C:\Users\drewm\Documents\R\win-library\3.4\rmarkdown\rmd\latex\default-1.17.0.2.tex" --highlight-style tango --latex-engine xelatex --variable graphics=yes --variable "geometry:margin=1in"' had status 43
I was able to repair the error with a simple example below:
test.r
library(rmarkdown) library(knitr) setwd(C:/something) render("Test.rmd", output_format=pdf_document(latex_engine="xelatex"), output_file="test.pdf")
Test.rmd
--- title: "Habits" output: pdf_document: latex_engine: xelatex --- Hello World!
I also see an error when I paste Test.Rmd directly into RStudio instead of using a separate .R file with render() . I also tried using the lualatex pdf engine and got the same error as above. I can create PDF files using the RMarkdown PDF example built into RStudio.
This Sourceforge post seems appropriate, but not useful, as the solution was to upgrade the fontspec package, and I am already using the updated fontspec package.
