mkLookup R Documentation
Create a lookup function to query locations against spatial masks
Description
Simple pixel spacing is used to overlay point locations on a spatial grid, or
a series of grids.
Usage
mkLookup(x, by.segment = TRUE)
Arguments
x
an xyz-list with matrix or array of masks
by.segment
logical - is the mask to be queried separately for each time step?
Value
A function, with one argument - a matrix of points - that returns a logical
vector indicating the overlay of each point against the masks.
Note
Very little error checking is done.
