No. R is not S-PLUS, and is `not unlike S'. Those are S-PLUS proprietary
extensions to S.  Given how little depends on them, I suggest you
look hard at the R `ts' class (which S does not have) as it does
much of what rts does in S-PLUS.

It does have sub and gsub that will do a lot of what you want, but I do
plan to add a version of regexpr fairly soon, as I miss it too.
