Have a look at
?array
its use in comparison to MATLAB's reshape is in fact described in the
Hiebeler-matlabR.pdf that Arien mentioned yesterday. If you want to
stick to MATLAB-like syntax, the matlab package has a function reshape
that should do exactly what you want:
Ok sure.

Dear Clément,
Thanks for your reply. Firstly, I struggled to find you a dataset
which shows it, because it seems it's not consistent. For example, for
two particular animals, the overlap is 0.8 when just
That's it. Thank you!

PS:
To let the example work actually before calling krige() you should run this
command:
names(SPgrid) - CL
Moreover the right krige call is the following:
pm10.rk - krige(as.formula(lm$call$formula), points, SPgrid,
rvar$var_model)

You are probably running an older version of R. See sessionInfo().

Dear list,
A brief and (hopefully) simplistic question regarding point pattern
analysis.
We have compiled a large, continental database of chemical burdens in a
model organism. Currently, the data span 40 years and covers the entire
country of Canada (including the high arctic). We have
Dear Researchers,
I have a points shapefile with wave shape. I wish to select only the border
points to create a border owin with the same wave shape. I tryed to use
convex.hull but the final shape is not the same. Some researchers have some
suggestions?
thanks

Thanks Rolf,
I see your point, and I admit that I've waffled a bit on this issue. I'm
hesitant to drive down the kriging path (although indicators might be
suitable), because there are many known (and unknown) covariates that affect
the contaminant burden, and few of these are quantified at the
