Summary of a Point Pattern Dataset
Prints a useful summary of a point pattern dataset.
Usage
## S3 method for class 'ppp':
summary(object, \dots, checkdup=TRUE)
Arguments
- object
- Point pattern (object of class
"ppp"
). - ...
- Ignored.
- checkdup
- Logical value indicating whether to check for the presence of duplicate points.
Details
A useful summary of the point pattern object
is printed.
This is a method for the generic function summary
.
If checkdup=TRUE
, the pattern will be checked for the
presence of dublicate points, using duplicated.ppp
.
This can be time-consuming if the pattern contains many points,
so the checking can be disabled by setting checkdup=FALSE
.
If the point pattern was generated by simulation
using rmh
, the parameters of the algorithm
are printed.
