Hello all,

I know this is a pretty easy question but I can't find it in S poetry or
R help.

How can I make a negative number positive. Such as
-5 to be +5
I tried +(-5), but that didn't work.

So no, I don't mean taking a -5^2 just to get a positive number.
This is in a function so it's not just -5 it's x. :)
