[R] random between two values

2009-08-06 Thread damien landais 
Hi,
I would obtain a random value between two (for example between 40.15 and 56.58 
I would have only one value).
I'm looking for a package/a function which could do this.
Could anybody help me please?

That's pretty straightforward to do - here's a simple function. The
exact behavior
at the edges is left as an exercise. :)

rbound - function(rmin, rmax)
{
   x - runif(1)
   x - x * (rmax - rmin) + rmin
   x
}

Or just use runif's built-in bounds:
thisMin-40.15
thisMax-56.58
runif(1,thisMin,thisMax)
