Paste a character to an object
Dear List,
I can't seem to get a simple paste function to work like I need. I have an object I need to call but it ends in a character string. The object is a list of home range values for a range of percent isopleths. I need to loop through a vector of percent values, so I need to paste the percent as a character on the end of the object variable. I have no idea why the percent is in

The problem is, hovever, that I need the vectorized isoplethes, as in
contour().
Unfortunately, I found no solution to get the internal data from
contour().
Is there a possibility to extract contour lines as x-y-polygon from a
grid without hacking plot3d.c?
Thank you in advance!

Resampling Help Needed
I am using package ks() to build 3D representations of bird territories and
calculate territory volume from spatial data (simply x, y, and z
coordinates). What I want to do is determine at what sample size (#
locations collected) does the territory volume stop increasing. This should
give me an idea of the number of points needed for future seasons.
So I have a couple of birds each with 200
