Simulated Point Pattern Lists

Description

Lists of simulated point patterns for illustrating the computation of barycenters.

Usage

pplist_samecard

pplist_diffcard

Format

Objects of class pplist, which are essentially lists of ppp-objects.

An object of class ppplist (inherits from solist, anylist, listof, list) of length 80.

An object of class ppplist (inherits from solist, anylist, listof, list) of length 50.

Details

pplist_samecard contains 80 point patterns of 100 points each. The patterns were independently generated from a distribution that creates quite distinctive clusters.

pplist_diffcard contains 50 point patterns with cardinalities ranging from 17 to 42. The patterns were independently generated from a distribution that creates overlapping clusters.

Examples

# plot the first eight patterns of each data set
plot(superimpose(pplist_samecard[1:8]), legend=FALSE, cex=0.4, cols=1:8)
plot(superimpose(pplist_diffcard[1:8]), legend=FALSE, cex=0.4, cols=1:8)
