5 ???????? 2023 ?. 19:02:56 UTC, Sukriti Sood <ssood at woodstockinst.org> ?????:>I uninstalled and reinstalled both R and RStudio themselves multiple times.Knitr lives separately from R and RStudio in a "library", most likely under your %userprofile%. Try using install.packages to install it anew. Can you load knitr from an RGui session? If yes, the problem might be elsewhere. -- Best regards, Ivan
