density.splitppp {spatstat} | R Documentation |
Compute a kernel smoothed intensity function for each of the components of a split point pattern.
## S3 method for class 'splitppp' density(x, ...)
x |
Split point pattern (object of class |
... |
Arguments passed to |
This is a method for the generic function density
.
The argument x
should be an object of class
"splitppp"
, effectively a list of point patterns.
Typically x
is obtained by applying
the function split.ppp
to a point pattern y
by calling split(y)
. This splits the points of y
into several
sub-patterns.
A kernel estimate of the intensity function of each of the
point patterns is computed using density.ppp
.
The return value is a list, each of whose entries is a
pixel image (object of class "im"
). The return value
also belongs to the class "listof"
and can be plotted
or printed.
A list of pixel images (objects of class "im"
).
Can be plotted or printed.
