...binary images). Point process models can be fitted to point pattern data. Cluster models are fitted by the method of minimum contrast. Very general Gibbs point process models can be fitted to point pattern data using a function ppm similar to lm or glm. Models may include dependence on covariates, interpoint interaction and dependence on marks. Fitted models can be simulated automatically. Also provides facilities for formal inference (such as chi-squared tests) and model diagnostics (including simulation envelopes, residuals, residual plots and Q-Q plots).

You are talking about random point patterns, since the glow-worms appear as ``stars'' (= points). See the package ``spatial'' (which comes with R) and try simulating a pattern using Strauss(). Or install the package ``spatstat'' from CRAN --- in this package there is a variety of ways to simulate ``regular'' random point patterns --- rMaternI, rMaternII, rSSI,

Dear all, I have discovered that there are many things that I used to do in my GIS which are easily done directly in R, for example calculating interpoint distances using geoR and pick out points inside a polygon using splancs. I now wonder, is there a function to create a line object like a watercourse and then calculate the distances between many points in space and this line? I couldn't find it in geoR, splancs, spatial or RArcInfo. Thanks...
