Description

Given a pick file in WPX format, break the picks apart clustered accoring to single link cluster analysis.

Usage

clusterWPX(twpx, tol = 200, PLOT = FALSE)

Arguments

twpx

WPX list

tol

tolerance in seconds - all pick distances less than tol will be set to zero to force these to be associated.
