reversing a scale

["Walter R. Paczkowski" <dataanalytics@earthlink.net>]

Hi,

I'm looking for a simple way to convert a scale such as 1, 2, 3, 4, 5 to
5, 4, 3, 2, 1.  In other words, I want to map

1 --> 5
2 --> 4
3 --> 3
4 --> 2
5 --> 1

So if I have a vector (5, 1, 3, 4, 2, 1, 1, 5), I want to map it to a new
vector (1, 5, 3, 2, 4, 5, 5, 1).  I've been using ifelse statements
which works but if my scale is, say, 1:100, then I have 100 nested
statements - that's not good.  Any suggestions?

Thanks,

Walt Paczkowski
