[R] sequence that counts up and back down

I hit a minor sticking point working one of the problems in 'Using R'
(Verzani). I'm having difficulty with generating a sequence that goes
1, 2, 3, 4, 5, 4, 3, 2, 1. I can make one that counts up, I can make
one that counts down, etc. but one that counts up then down like this
(short of just using c() ) is stumping me.
Any help (on or off list) would be appreciated.
