for generic functions: a dspat object output from |
object |
a dspat object output from |
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 |
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 |
