Dear Listers,

Everybody is probably used with sp:spsample, which permits to produce

points locations at random or on a regular grid. Is anybody aware of a

package permitting similarly to produce points locations in a field with

various degrees of clustering. The idea is to produce points in a field

with various degrees of clustering repetedly, and to compare statistics

to observed data. E.g. observations in the real world are clustered;

one computes a statistics, e.g. the distance of each observation to a

feature (e.g. to a road network); then one compute B=999 similarly

clustered distributions randomly and the corresponding statistics. This

would allow to compute how likely the observed statistics is.

Any hint welcome!

Best,

Patrick
