Question

How to conveniently spellcheck R comments with RStudio on R source files?

I am writing a package and I want it to look professional. Thanks to Oxygen, all package's documentation lives in R comments, which by default is excluded from spell checking. So even if spell checking functionality does exist in RStudio, I don't know how to use it.

Answer 1

The spelling package is great for this: https://github.com/ropensci/spelling.

devtools::install_github("ropensci/spelling")
spelling::spell_check_package() # path to package Project

Answer 2

RStudio 1.3 will include this feature; and it is possible to already try it out.
