Mark Connection Function for Multitype Point Pattern on Linear Network
Description
For a multitype point pattern on a linear network,
estimate the mark connection function
from points of type i
to points of type j
.
Usage
linearmarkequal(X, r=NULL, ...)
Arguments
X |
The observed point pattern,
from which an estimate of the mark connection function
|
r |
numeric vector. The values of the argument |

Arguments passed to |
Details
This is the mark equality function
for a point pattern on a linear network (object of class "lpp"
).
The argument r
is the vector of values for the
distance r
at which p_{ij}(r)
should be evaluated.
The values of r
must be increasing nonnegative numbers
and the maximum r
value must not exceed the radius of the
largest disc contained in the window.
Value
An object of class "fv"
(see fv.object
).
