Internal: Internal DSpat functions

Description

Miscellaneous set of functions used in the package.

Usage

"AIC"(object,...,k)
"print"(x,...)
"summary"(object,...)
"coef"(object,...)
"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
