In the latest GUI (1.31-rc) you can enable external browser for the help pages by setting the use.external.help preference to YES. It's not recommended (since it sort of disables the help system), but for those that requested it it's now possible.


to enable (in Terminal):
defaults write org.R-project.R use.external.help YES

to revert to default:
defaults delete org.R-project.R use.external.help

> Good point. We're intentionally overriding the "browser" option in the R.app GUI because help pages are treated differently from other "regular" browseURL calls. However, it may make sense to allow a user override. I'll look into this. You will, however, lose the built-in help feature so I would not recommend it as the default.
