Over the past week my rmarkdown installation won't compile .rmd files to pdf - these files worked prior to 1 December. Compiling to html and Word is fine, only pdf. The R Markdown console seems to run through the compilation normally, prints (in blue) the name of the output file (.md) and then appears to execute pandoc but it hangs. No message, no output, nothing (I let it go 45 minutes). I kill the job and then have to delete the temporary files. But no pdf is produced. I've just un- and reinstalled MikTex 2.9 and R studio, updated the R libraries and no improvement. I'm not sure where to go from here. Any help is appreciated. It does this for any .rmd file, including the template when one creates a 'new' Markdown document in RStudio. Here're the console contents
