derstand what you
mean. The help file gives journal paper references, and indicates that the code
in pcf3est calculates the estimator described in the paper by Baddeley et al
(1993). I am the author of the technical paper, the code, and the
documentation. What exactly are you disputing?

Subject: Re: [R] empty density plot for point pattern in spatstat
Let me
by running 'example(plot.im)' or
setting col=grey(seq(0,1,length=32)) in the call to plot.im
Try setting 'useRaster=FALSE' in the call to plot.im.
Let me know if any of these work. If not, let's talk on skype
to figure it out.

=20 then the significance level is
1/21 = 4.8% (one-sided) or 2/21 = 9.5% (two-sided).
If you want a significance level of 5%, you need either
nsim=19 (one-sided) or nsim=39 (two-sided).

If 'X' is a data frame containing columns 'x', 'y' and 'value, try
m - with(X, tapply(value, list(y,x), all))
z - im(m, xcol=sort(unique(X$x)), yrow=sort(unique(X$y)))
w - as.owin(z)
This will only work if the x, y values form a rectangular grid in some
order.

Improved numerical stability, in mixed-gas case.
The return value of ndl now has an attribute
which identifies the controlling tissue.
showstates
Improved plot labels.

Incidentally, please be warned that there is a bug in the plot method
plot.quadratcount in spatstat 1.14-4 which causes the counts to be
plotted in the wrong quadrats. This will be fixed in the next release
spatstat 1.14-5, due shortly.

In spatstat you can use the command 'smooth.ppp' to perform
kernel-weighted spatial interpolation. If the insect counts are small,
then it would be more appropriate to do spatial Poisson regression
(using other packages).
