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 to points of type
.
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 |

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 at which
should be evaluated.
The values of
must be increasing nonnegative numbers
and the maximum
value must not exceed the radius of the
largest disc contained in the window.
Value
An object of class "fv"
(see fv.object
).
