It doesn't exist, but it can always be replaced by if() {} else {}
constructs. (You don't usually see goto in the class of "functional
programming languages" to which R belongs.  See also
http://en.wikipedia.org/wiki/Edsger_W._Dijkstra .)

R does have break, next, and return() which cover some common cases
where goto might be used with some reason.
