Fellow Users,

In Spatstat, if you have a ppp object with, say 100 points, how do you create another ppp containing a random selection, N, of the original?

You can tell the function 'rthin' to make a sub-selection of points, i.e. "every point is removed with probability 0.5" but you CAN'T set N exactly...

I'm sure this should be easy...
