[R] Boundaries of consecutive integers

[Lizzy Wilbanks]

Hi folks,

I'm trying to accomplish something that seems like it should be
straightforward, but I've gotten tied in knots trying to figure it
out.  A toy example of my issue is below.  I've played with diff and
can't seem to figure out a systematic solution that will give me the
two column output independent of the number of breakpoints in the
vector...

test<-c(1:5, 22:29,33:40)
example.output<-matrix(c(1,5,22,29,33,40),nrow=3,ncol=2,byrow=TRUE)


Any ideas?


Thanks!
Lizzy
