# Error message when I try to knit the R markdown code

When I try to knit my r markdown to HTML, I got the following error message. Please help.
pandoc.exe: \: openBinaryFile: invalid argument (Invalid argument)
Error: pandoc document conversion failed with error 1
Execution halted

Hi,

This means that a file is not found somehow. It could come from several place.
Can you share a more detailed example that reproduce the issue ? Or at least give some details about your environment ?

FAQ: How to Format R Markdown Source

Thanks for the reply. I am using window10. This is the location.
"C:/Users/fyan/AppData/Local/Pandoc/pandoc" +RTS -K512m -RTS Geospatial-raster.knit.md --to html4 --from markdown+autolink_bare_uris+tex_math_single_backslash --output Geospatial-raster.html --lua-filter "\fshome01pd\fyan$\Documents\R\win-library\4.1\rmarkdown\rmarkdown\lua\pagebreak.lua" --lua-filter "\fshome01pd\fyan$\Documents\R\win-library\4.1\rmarkdown\rmarkdown\lua\latex-div.lua" --self-contained --variable bs3=TRUE --standalone --section-divs --template "\fshome01pd\fyan$\Documents\R\win-library\4.1\rmarkdown\rmd\h\default.html" --no-highlight --variable highlightjs=1 --variable theme=bootstrap --mathjax --variable "mathjax-url=https://mathjax.rstudio.com/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML" --include-in-header "C:\Users\fyan\AppData\Local\Temp\RtmpQnPeKs\rmarkdown-str47141913a79.html" I see that in your file paths. Are R and R packages installed on a network drive ? R Markdown and Pandoc does not play well with that unfortunately. I could depend on your Pandoc version also. It may be something else though as I don't recognized this error message. But could be related to this type of file paths Thanks for the quick reply. I am pretty sure my R installed at my C drive. Thank your R Library where packages are installed is on a network drive maybe. Do you recognize the start of this path where files from the rmarkdown packages are looked for ? I believe this is what is causing the issue. THis will give you the path of your  .libPaths() find.package("rmarkdown")  can you check ? Thanks. This is what I got .libPaths() [1] "\\fshome01pd/fyan$/Documents/R/win-library/4.1"
[2] "C:/Program Files/R/R-4.1.3/library"
find.package("rmarkdown")
[1] "\\fshome01pd/fyan$/Documents/R/win-library/4.1/rmarkdown" Ok so that confirms what I said. Your packages are installed in this PATH Do you recognized \\fshome01pd/fyan$/ ? It seems like your personal folder you HOME is on a network drive. Is that the case ?

Sorry for the late reply. I think that is the case. What should I do to fix it?

If possible, you should use a local disk for this.

Otherwise, it would help if you can map your network drive to a letter on your Windows machine.
