R help - Aug 2012 - Fwd: Need help

Dear colleagues.

I wonder if anybody knows about a procedure in R to calculate the
Berger-Parker index and the Brillouin Diversity index.

I searched the net but did not find anything good about it.

Thanks a lot for any help

Mayo, Elvira.

Hello,

An excelent alternative to Google is package 'sos'.

#install.packages('sos')
library(sos)

 > r1 <- findFn('Berger-Parker')
found 2 matches
 > r2 <- findFn('Brillouin')
found 0 matches
Warning message:
In findFn("Brillouin") : HIT not found in HTML;  processing one page
only.

 > r1  # open a browser window with the two matches. The first is: 
BiodiversityR::diversityresult

 From the help page:
index - [...] "Berger" to calculate the reciprocal Berger-Parker 
diversity index, [...]

Hope this helps,

Rui Barradas

Dear Elvira,

The RandForestGUI estimates the Berger-Parker dominance index.
Regarding the Brillouin Index, I found that someone posted the same question
here earlier this year:
http://tolstoy.newcastle.edu.au/R/e17/help/12/01/1132.html The answers in the
thread may help you.
 
Regards,

Jos?
