PMulti: A function to compute multi-group normalised exposure (PMulti)
Description
The multi-group normalised isolation index is a
multi-group version of the isolation index (xPx)
Usage
PMulti(x)
Value
multi-group normalised isolation index
Arguments
x
- an object of class matrix (or which can be coerced to that class),
where each column represents the distribution of a group within
spatial units. The number of columns should be greater than 1 (at least 2
groups are required). You should not include a column with total
population, because this will be interpreted as a group.
