The knit button in my Rstudio has stopped working, throwing the error below:
Error in loadNamespace(name) : there is no package called 'rmarkdown' Calls: :: ... tryCatch -> tryCatchList -> tryCatchOne -> <Anonymous> Execution halted
I have followed the suggestions from here, here, here, here, here and here. To summarise, they mostly suggest checking library permissions (no issues) and reinstalling rmarkdown and various other packages (tried with no difference).
Running rmarkdown::render() still works. Does anyone have ideas as to why the knit button doesn't??
