The Harte lab at the University of California, Berkeley, is seeking a lab
technician to contribute to several exciting new projects involving the
testing of ecological theory and the development of scientific and
conservation-oriented software. The position will be part of a collaborative
effort ba
Hi Alejandro,
Here are some thoughts on your question: ANOSIM analyses the similarity
(e.g. Bray-Curtis, Jaccard, etc.) between community samples. So it's kind
of like a multivariate analysis of variance. In general such a result
cannot be obtained using an analysis of variance. So that might e
Hi Rajasri,
Sorry for coming to this late. Is your concern that in the case of small
patches you've sampled completely, but in the case of large patches, some
species may have gone undetected?
If that's the case, using Chao's indices might be a good option. They try
to take account of "unseen"
looking at the documentation, it seems `prestondistr' returns you the
coefficients of the distribution, but not a random sample from that
distribution.
colony size is discrete, yes? so really you want to sample numbers 1, 2,
, MAX
you could do that with something like:
trunc <- 20
Hi Emma,
I don't know really. I always use the built-in editor that comes with R.app
which I've found useful enough (no split screen but some highlighting plus
piping selected code with apple+enter).
But as it turns out there's a whole discussion about text editors on the
r-sig-eco email list (I
Fulbright is a great option, especially for research abroad.

The only bummer there is that I think the aplication deadline is coming up
real soon. To apply you usually need to have some kind of "affiliation" in
the states--but for those who just graduated
Hi Jane,
I think someone may have asked something similar on the r-sig-eco email list
(which is a good resource in general:

I think the answer may have been there there's a function in the vegan
package for R (http://cran.r-project.org/web/pack
Hi Madhu,
Seems tricky! I think you might be best served by using explicitly circular
methods for your circular data. I don't really know anything about such
things (so why I'm responding to your post, I don't know!) but what little
information I've gathered leads me to believe that you could us
