I am troubleshooting a less-experienced R user's issue. She is attempting to knit a report that I created. The error started after her laptop was re-imaged, and R/RStudio had to be re-installed. Previously she could knit the report, and I can still knit the file without an error. The error occurs when it tries to create the file-- it's not an issue with the code. The normal procedure for knitting is to run a .R script, with rmarkdown::render() knitting the html and then writing it out to a different location with a different name. If she manually knits the .Rmd she still gets the error but the .html file with the same name as the .Rmd gets created.
rmarkdown::render("CODE\\SPEECHMINER_MAINTENANCE.RMD", output_format = "html_document", output_dir = "OUTPUT", output_file = paste0("SPEECHMINER_MAINTENANCE_REPORT_", format(Sys.Date(), "%Y-%m-%d"), ".html") ) Below is her session info. As I said earlier, everything is up-to-date because they had to do a fresh install. Her RStudio is 1.2.x, I can get that if necessary.

In this case the update precipitated the problem. My system is not as updated. I'm on R 3.4.4, RStudio 1.1.x, knitr 1.22 and rmarkdown 1.12. I don't know much about how pandoc works and I'm thinking that must be the issue-- I'm sure that many folks are able to do this process successfully with the updated versions of R/RStudio/the packages.
