An object of class "influence.ppm"
.
Optional. Domain of integration: a window (class "owin"
)
or a tessellation (class "tess"
).
Additional arguments. See Details.
Logical value indicating what to do if the data cannot be
converted to a window. If fatal=TRUE
(the default)
an error occurs. If fatal=FALSE
a value of NULL
is returned.
A window (object of class "owin"
) for
as.owin
, domain
and Window
.
A point pattern (object of class "ppp"
) for
as.ppp
. A numeric value or numeric vector for integral
.
A pixel image, or list of pixel images, for Smooth
.
These functions are methods for the class "influence.ppm"
.
An object of this class
represents the influence measure of a fitted point process model
(see influence.ppm
).
For as.ppp
, domain
, integral
and Window
,
additional arguments (…
) are ignored.
For as.owin
and Smooth
,
additional arguments are passed to the method for class "ppp"
.
