[R] Ecological Niche Modelling on R

[stephen sefick]

that is a pretty big question.  And I am not qualified to answer it,
but my suggestion- from figuring out how to use other things- is to
find out how other people have modeled ecological niches- not
necessarily with R,  and then try and find out functions that preform
the pieces or the whole analysis.  I believe there is a book out there
about modeling ecological niches with R.  I did  a google search for
that and this is what I found:
http://www.zoology.ufl.edu/bolker/emdbook/.  I don't know if this
helps, but maybe it will.  Good luck.

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
