Given a point process model that has been fitted to spatial point pattern data on a linear network, this function extracts the design matrix of the model.

extracts the model matrix for the GLM.
The result is a matrix, with one row for every quadrature point in the fitting procedure, and one column for every canonical covariate in the design matrix.
If there are
NA values in the covariates,
keepNA determines whether to retain or delete
the corresponding rows of the model matrix. The default
keepNA=TRUE is to retain them. Note that this differs from
the default behaviour of many other methods for
which typically delete rows containing
A matrix. Columns of the matrix are canonical covariates in the model.
Rows of the matrix correspond to quadrature points
