This is a fast alternative to the SpatialPointsDataFrame. It is meant to replace
that functionality, though there are not as many methods (yet). The object is primarily
a numeric matrix. Any character column passed to ... will be converted to a numeric,
as.factor internally, and stored as a numeric. Methods using this class
will automatically convert character queries to the correct numeric alternative.
agentMatrix(..., coords) # S4 method for matrix agentMatrix(..., coords) # S4 method for missing agentMatrix(..., coords)
Vectors, a data.frame, or a matrix of extra columns to add to the coordinates, or a SpatialPointsDataFrame.
A matrix with 2 columns representing x and y coordinates
