LSimpson: A function to compute local Simpson's index
In OasisR: Outright Tool for the Analysis of Spatial Inequalities and Segregation
LSimpson R Documentation
A function to compute local Simpson's index
Description
Local Simpson's interaction index measures the probability
that randomly selected individuals are not in the same group in
each spatial unit.
Usage
LSimpson (x)
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.
Value
A vector containing the local Simpson's interaction index values
for each spatial unit
References
Simpson E. H. (1949) Measurement of diversity.
Nature 163:688

Other local indices: LQ,
HLoc, LShannon
Examples
x <- segdata@data[ ,1:2]
LSimpson (x)
