Prepare geospatial data and covariates (contained in hwa_wombling.zip) for use in WinBUGS 2. Call WinBUGS code (using R2WinBUGS package) for the areal and local-edge wombling models. 3. Read output from WinBUGS and calcualte boundary probabilities. 4. Make maps of output that highlight boundary probabilities. "womblingFuncs.R" : R code containing helper functions for plotting, etc called by code in womblingRcode.R.<br> <br> "areal_wombling.bug" : This file contains WinBUGS code to fit a Bayesian areal wombling model.<br> <br> "local_edge_wombling.bug" : This file contains WinBUGS code to fit a Bayesian local edge wombling model. <br>
