Bounding Box for a Spatial Point Pattern
DESCRIPTION:
Generates a bounding box for a list of points in particular for an
object of class
spp
.
USAGE:
bbox(x, y)
REQUIRED ARGUMENTS:
- x
-
an object of class
"spp"
, a spatial point pattern object.
It could also be a list with named components
"x"
and
"y"
or
a vector of x-coordinates when argument
y
is given.
OPTIONAL ARGUMENTS:
- y
-
numeric vector. Needed if
x
is a vector in which case it must have
the same length as
x
.
VALUE:
a list with two named components
"x"
and
"y"
containing the
coordinates of the corners of the bounding box of the data in
x
(and
y
, if given).
EXAMPLES:
bbox(lansing)
maples <- spp(lansing[lansing$species == "maple",],drop=T)
bbox(maples)
