Internal DSpat functions

Description

Miscellaneous set of functions used in the package.

Usage

## S3 method for class 'dspat':
AIC(object,...,k)

## S3 method for class 'dspat':
print(x,...)

## S3 method for class 'dspat':
summary(object,...)

## S3 method for class 'dspat':
coef(object,...)

## S3 method for class 'dspat':
vcov(object,...)

x.psp==y.psp

x.psp!=y.psp

rev_val(x,y,val)

im.clipped(x, window)

owin.gpc.poly(window)

Arguments

x for generic functions: a dspat object output from dspat with class dspat, for rev_val: a vector of x coordinates, for im.clipped: a vector of image values in order defined by spatstat
object a dspat object output from dspat with class dspat
k penalty per parameter in AIC, default is 2
x.psp, y.psp psp objects
y vector of y coordinates
val vector of image values
window class owin polygonal window
... additional arguments for generic functions

Details

Internal functions:

AIC Computes AIC value
print.dspat print various objects in dspat object
summary.dspat shows summary of ppm model object
coef.dspat provides coefficients of the intensity and detection function
vcov.dspat provides var-cov matrix of coefficients
Ops.psp provides == and != operators for psp objects
rev_val reverses order of val such that y increases within increasing x as needed in im
im.clipped creates image and fills values (val) into the clipped portion
of the image as defined by window
owin.gpc.poly creates a gpc class poly from first polygon of an owin class
