I recently upgraded R to 4.0.5 and Rstudio to Version 1.4.1106.
When I run *.rmd files that executed fine previously they work fine when I execute them within Rstudio chunk by chunk. However, when I try to knit them to an html file I get the following error:
output file: VISSIMTravelTimer2.knit.md
Error: 'set_envvar' is not an exported object from 'namespace:xfun'
I have tried to delete the rdata file. and also set any write statements to use the full rather than relative paths.
Nothing seems to work, and the knit fails for all projects that I have previously stored.
What can I do to fix this?
Also, where is the above output *.md file stored.
