"Rendering R Markdown documents requires updated versions of the following packages: glue, highr, knitr, magrittr, markdown, stringr, tinytex, xfun, yaml." When I press "yes" to install these packages it does not install and an error message appears. Has anyone had this problem and if so how did you rectify this? I tried downloading tidyverse and the dlpyr but hasn't seemed to help??? Any suggestions would be much appreciated.
