"ppp"
), a three-dimensional point pattern
(object of class "pp3"
), or a
general multidimensional space-time point pattern
(object of classppx
objects).x
, or a numeric matrix or data frame with one row
for each point in x
.coords
returns a data.frame
with one row for each point,
containing the coordinates.
coords<-
returns the altered point pattern.coords
extracts the coordinates from
a point pattern. The function coords<-
replaces the coordinates
of the point pattern with new values.
Both functions coords
and coords<-
are generic, with methods for
the classes "ppp"
) and "ppx"
.
An object of class "pp3"
also inherits from "ppx"
and
is handled by the method for "ppx"
