I am new to Rstudio, so this issue is likely very straightforward. I cannot knit my RNotebook document to a PDF. When I go to knit the document, I receive the following error :
Calls: <Anonymous>...eval_with_user_handlers -> eval -> install.packages -> contrib.url
I have installed contrib.url and tried to load the package using library(contrib.url), however this does not seem to be working.
