Bivariate pair correlation function for a given distance r
1 | PCFr(X, spec.1, spec.2, n.iter, radius.seq)
|
X |
Object of class 'ppp' (from 'spatstat' packge). This is a marked point pattern in which each mark gives identity of a species. Thus, the object must have at least 2 species. |
spec.1 |
Character string indicating name of species 1 in the 'ppp' object. |
spec.2 |
Character string indicating name of species 2 in the 'ppp' object. |
n.iter |
Number of iterations for simulation from a homogeneous Poisson point process. |
radius.seq |
Numeric vector. Sequence of radii for which the pcf function should be calculated |
A list.
