These functions are methods for the generic commands
`print`

,
`predict`

and
`plot`

for the class `"rho2hat"`

.

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 `plot.rho2hat`

displays the estimated function
\(\rho\) using `plot.fv`

, and optionally
adds a `rug`

plot of the observed values of the covariate.
In this plot the two axes represent possible values of the two covariates.

The method `predict.rho2hat`

computes a pixel image of the
intensity \(\rho(Z_1(u), Z_2(u))\)
at each spatial location \(u\), where \(Z_1(u)\)
and \(Z_2(u)\) are the two spatial covariates.
