Description

Estimates the L function

Usage

L.r(X, r, ReferenceType = "", NeighborType = "")

Arguments

X

A point pattern (ppp.object), marks must be a dataframe with two columns: PointType: labels, as factors. PointWeight: weights.

r

A vector of distances.

ReferenceType

One of the point types. Default is all point types.

NeighborType

One of the point types. Default is all point types.

Value

• A vector containing L(r) values.

Details

L is the normalized version of K: $L(r)=\sqrt{\frac{K}{\pi}}-r$.
