Define Similarity Matrix
Description
weight.taxo computes a matrix whose entries [i, j] are set to 1
if x[i] == x[j], 0 otherwise.
weight.taxo2 computes a matrix whose entries [i, j] are set to 1
if x[i] == x[j] AND y[i] != y[j], 0 otherwise.
The diagonal [i, i] is always set to 0.
The returned matrix can be used as a weight matrix in
Moran.I. x and y may be vectors of
factors.
See further details in vignette("MoranI").
Usage
weight.taxo(x)
weight.taxo2(x, y)
Arguments
x, y |
a vector or a factor. |
