[R] R crashes with >kud<-kernelUD(data, h="LSCV") script

[R. Michael Weylandt]

Hi Amanda,

I can't reproduce this without your data set. Would it be possible for
you to give us dput(head(data, 20)) if you need further help?

Also, if you could supply the output of sessionInfo()? That's often
helpful for anything that "crashes" [that term means many things to
different people so if you could be more specific that'd be great as
well]

Finally, you may with to get in touch with the maintainer of the
adehabitatHR package directly. You can get contact info by typing
maintainer("adehabitatHR") at your prompt.

Best,
Michael
