Yep, I did. Got nothing. It does not come with R 3.4.3, which is the version I

R CMD Rdiff comes with this version, but it is a shell command not a R 
function. It is meant for diff'ing R output.

It's in the tools package, so ?tools::Rdiff should get what you want even in that version. But as you note, it isn't a general purpose diff for character vectors, it is targeted at comparing R output files.
