All, I'm having difficulty kniting my rmarkdown file. Error message is below. I'm using the latest R version, I've loaded MikTex and installed- tinytex::install_tinytex(), but no luck. Any help would be appreciated.
Error in contrib.url(repos, "source") :
trying to use CRAN without setting a mirror
