follow up relevant information.

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.

Two other comments:
(1) for efficiency you can replace sin(abs(m1-m2))^2
by sin(m1-m2)^2.
(2) if you take nsim=20 then the significance level is
1/21 = 4.8% (one-sided) or 2/21 = 9.5% (two-sided).
If you want a sign
returns the optimized (average or maximum) distance.
There are related functions pppmatching and matchingdist which will
create other kinds of pairings and measure the associated distances.
These functions were written by Dominic Schuhmacher.

Dear users,
I am trying to export polygons from Arcmap into Spatstat to run some

One particular area to be exporte

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,
atially interpolating the
insect counts (number of trapped insects) observed at these locations.
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
