[R] question about message

[Jeff Newmiller]

Please keep your posts on the mailing list... I don't do one-on-one consulting without a contract.

Please carefully re-read my last email and follow its advice before posting again. You may yet have a problem that is on topic here, but until you can give us a reproducible example that runs or fails in R we won't be able to tell.

I will venture to guess that you ought to install and configure LaTeX as suggested on the RSTUDIO website if you want that error to go away... but that is not an R-help topic, and your questions don't indicate that generating PDF files is what you really want to be doing.
