[R] About Torus Rndamiztion

[MORNEAU François]

Hello Surendra,

To answer to Ben, Kyle Harms actually wrote his code in R. I would advise you to ask him directly. He kindly shared his code with us when we asked him.

I can also propose you to discuss off-list of our own version of this code, slightly modified to deal with multi-plots situations if you are interested.

Regards,

François Morneau

  I know the work you're referring to, but I don't know
whether Harms wrote the original code in R (quite possibly)
or whether someone has translated it (also quite possible).
"Someone told me there was a function in Utility.r" (freely
translating from your post) isn't enough information
for us to go on ... why don't you go back to whoever
told you and ask for more information?  Or write
to the author and ask him?

  Here are a couple of the results of RSiteSearch("torus")
that are likely to be relevant to your question
(especially the second).

  You might also try further queries on the r-sig-eco list
or the r-sig-spatial list, since this is a fairly specialized
question ...

  good luck
