rarefaction curves: unable to run the R script from Gimlet
Hi everybody,
i'm trying to draw rarefaction curves to estimate a population size from
genotyped faeces.
I used the Gimlet software which gave me a script and a "rarefaction.txt"
file. I've copied both files in the work directory of R.
I changed library(nls) by library(stats) in the script.
But now, i'm still unable to run it.
If i ask to show error messages, the software

Extrapolation of rarefaction curve
Hi all,
I used R (vegan package) to make rarefaction curves and I calculated the
Chao index for each curve. However, the plateau is far from reached.
What I want to do now is the following:
Based on the Chao index, I want to extrapolate the curve so I get an x-value
which gives me an estimation of the total number of clones I'd have to pick
up and sequence in order to have a full coverage of

North Arrow (.png file) on a Map
Hi list.
I would like to know how do I insert a North arrow, stored as a png file in
my computer, in a map? I found lots of post asking similar things, one of
them mentioned the pixmap package. The map was done using map() and
shapefiles (the code is below). I’m using the pixmap () and addlogo()
functions. Well I can import the png with pixmap() function (I guess, once
there’s no error message),

rarefaction variance
Here's a question for ecologists on the r-help list-- I'm addressing this
to ecologists in particular because they're most likely to be familiar
with the equation in question but I'll be happy to discuss the problem
with anyone who's willing to take a whack at it.
I'm trying to write a function to calculate the large sample variance of
species richness estimates by

Doubts about mixed effect models
Hi everyone!
I have some doubts about mixed effect models and I hope someone could help
me. I´m trying to analyze a dataset coming from samples of dung beetles in
the same forest fragments along 3 consecutive years (1994, 1995 and 1996)
and 14 years after (2010). I sampled dung beetles in 18 different fragments
with different sizes and different degrees of isolation. My aim is to

Modelo para datos de conteos (Manuel Spínola)
Una distribución binomial negativa podría ser adecuada. De hecho, una
extensión de la binomial negativa, como la distribución de Waring
generalizada, termina convergiendo a una distribución binomial negativa.
Puedes ver que la mejora en la bondad del ajuste de la binomial negativa
con respecto a la Poisson es sustancial (te muestro también las salidas.).

How to order the levels os factor not by alphabetic order but by mean of Y.
Somethink like this:
I have this alphabetic order:

the order by mean os yvar is:

Ask help
Hello!
I am eager to learn if I only have a data about the relationship between otu and sample, could I use the function capscale, and final make a point plot that x-axis is CAP1 and y-axis is CAP2? Besides, what function could I use to make the different rarefaction curve with different color in the a plot in R? Appreciate very much.

Error in library (nls)
Hi everybody,
I'm not very experienced with R software. I have used it several times for
some of the population genetics analyses. I have problem with executing one
of the script. The script is created by another software called Gimlet and
it is aimed to calculate rarefaction curve in R software.
However, when I try to execute the script, it says: *Error in library(nls) :

Opus 1.3 different default bitrate between opus encoder and opus multistream encoder
I use the Opus multistream encoder for both mono and stereo encodings and after updating from 1.1.3 to 1.3 I noticed the size of the produced Opus files had doubled for 1-channel encodings whereas switching to the standand Opus encoder gave me roughly the same sizes as before. In these tests, I'm encoding an 8kHz mono stream containing only speech with the following options set:

The RV coinertia coefficient to interpret multivariate analysis plots
Dear all community,
My issue is related to the R package (made4) that permits me to calculate
the RV coefficient of co-inertia. However, it is a theoretical question.
And if I am not mistaken, the list Usenet groups sci.stat.consult is not
currently active.
Let me explain briefly:
Through different microbiota datasets, I have plotted PCoA, db-RDA and

Problem with object inside a function
Hi all,
I have a problem with an object inside a formula in a function that I make.
I create an object named qvartemp. This object is OK, look the levels:
> print(levels(qvartemp))
[1] "baixomedio" "alto"
Now I create a new object with a new formula:
> new.form <- as.formula(gsub(qvar,"qvartemp",as.expression(mma$formula)))
Look this new object:
