I have recently updated r, and when i tried creating a new rmarkdown it wasn't working so I tried installing the rmarkdown which also won't work. I was getting the code below:
Warning in install.packages : unable to access index for repository http://cran.rstudio.com/src/contrib: cannot open URL 'http://cran.rstudio.com/src/contrib/PACKAGES' Warning in install.packages : package ‘rmarkdown’ is not available (for R version 3.6.1) Warning in install.packages : unable to access index for repository cran.rstudio /bin/windows/contrib/3.6: cannot open URL
This suggest R is having connectivity issues, is your internet connection behind a proxy server or firewall? That is usually the case when you are at work or school.
Another thing to try is to disable secure HTTP option
Thank you! The issue was the proxy server or firewall - it worked when I tried again when left work.
