Undefined control sequence in rticles::tf_article output: when used with tinytex package

[jooyoungseo]

I cannot render an Rmd file using rticles::tf_article output format along with tinytex package.

Please help me with the issue using the following reproducible scripts:

tinytex:::is_tinytex()
#> [1] TRUE
options(tinytex.verbose = TRUE)

file <- rmarkdown::draft(
  "test", 
  "tf_article", 
  "rticles", 
  create_dir = TRUE, 
  edit = FALSE
)

rmarkdown::render(input = file, output_format = "rticles::tf_article")
#> processing file: test.Rmd
#> output file: test.knit.md

Looks like you have spaces in your path.

[jooyoungseo]

Thanks for your comment @tcgriffith; however, I do not think it has something to do with spaces in path. Because the path is automatically quoted with the quotation (") mark when generated by reprex::reprex() function.
If someone could try with the reproducible code with tinytex package on Windows system, please share me with your results.

[tcgriffith]

I tested your code and it's totally fine on Win10.

I'm still suspecting it's a path issue since you are using the template Rmd document. Please try the following script and see if it works for you, the only change I made is to change your working directory to c:

options(tinytex.verbose = TRUE)

setwd("C:")
file <- rmarkdown::draft(
  "test", 
  "tf_article", 
  "rticles", 
  create_dir = TRUE, 
  edit = FALSE
)

rmarkdown::render(input = file, output_format = "rticles::tf_article")

[jooyoungseo]

@tcgriffith, still doesn't work.
What version of Pandoc do you use? I use the latest one: V2.7.3.

[tcgriffith]

2.3.1. I never installed pandoc myself so I'm sure it was shipped with Rstudio.

[jooyoungseo]

It doesn't work even I tried with Pandoc 2.3.1.
Excuse me, @yihui, do you have any suggestion on this issue?

[yihui]

Yes. The problem came from the Rmd template, which I just fixed via 243e1b8. Somehow I didn't notice this when I was reviewing @dleutnant's PR #218 (FYI, knitr::fig_chunk() would be a much better way than pdf(tempfile()): https://yihui.name/en/2017/09/knitr-fig-chunk/).
