Error in loadNamespace(name) : there is no package called 'evaluate'

Question

While adding code chuncks to my .rmd file a la:

```{r} %code chunck

```

it can't be compiled anymore, and i get a loadnamespace(name) error:

Error in loadNamespace(name) : 
there is no package called 'evaluate' calls:<Anonymous> ... tryCatch-> Trycatchlist->trycatchoone

Has anyone ever experienced it? And how do I resolve it?

Answer 1

Try install.packages("evaluate") and then reattempt compilation. It was probably uninstalled unintentionally at some point.
