An object of class "rho2hat" is an estimate
of the intensity of a point process, as a function of two
given spatial covariates. See rho2hat.
The method predict.rho2hat computes a pixel image of the
intensity rho(Z1(u), Z2(u))
at each spatial location u, where Z1(u)
and Z2(u) are the two spatial covariates.
For predict.rho2hat the value is a pixel image
(object of class "im").
For other functions, the value is NULL.
