Usage
## S3 method for class 'ppm':
logLik(object, ...)
Arguments
object
Fitted point process model. An object of class "ppm".
...
Ignored.
Details

The maximised value of the log likelihood for the fitted model (as approximated by quadrature using the Berman-Turner approximation) is extracted.

If object is not a Poisson process, the maximised log pseudolikelihood is returned, with a warning.
