When I try to use r-markdown, my output fails. This occurs for all output formats, and irrespective of file content. I cannot see a preview. Nothing in the viewer panel in r-studio. This is the error I get:
openFile: permission denied (Permission denied)
Error: pandoc document conversion failed with error 1
I tried uninstalling/re-installing r and r-studio. I also disabled my google-drive and drop-box, in case they were interfering somehow.
What else should I try?
