The spatstat package has facilities for exploratory analysis of point patterns on a linear network (see help for 'lpp'). A special case is a point pattern on a single line. See help(spatstat) under 'Linear Networks' for a list of functions available. Of course if you are willing to assume the points are Poisson, and you want to distinguish CSR from inhomogeneous Poisson, you can do this with standard methods for random variables - e.g. the Kolmogorov-Smirnov test of goodness-of-fit to the uniform distribution; density estimation in 1D; etc Adrian Baddeley _______________________________________________ R-sig-Geo mailing list R-sig-Geo@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-geo
