[R] matching coordinates

[sethlatimer]

I am trying to implement the so called pivot algorithm for a markov chain
monte carlo simulation of self avoiding random walks.  There must be a
simple method of checking to see if the pivoted portion of the random walk
intersects with the previous section?

In other words I have a list of adjacent coordinates divided into two parts.
I apply an orthogonal transformation to one part and I need to check if it
intersects with the other part before accepting the transformation. I am
able to do it with a messy nest of loops but there must be a more elegant
solution that I am missing.

Thanks
Seth Latimer
