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

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

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),

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

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 determine

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.). datos<-c(1280, 1262, 1290, 1321,

Hi, I continue testing rKward. I dont know how to save the results from a script execution without use copy and paste or using a rkward output system. Now I try to understand how adapt my script do use the rKward output system. Example: I have this script: ---------------------- ## Carregar a tabela de riqueza e equitabilidade library(gdata) dadosriq <-

Hi, How to order the levels os factor not by alphabetic order but by mean of Y. Somethink like this: I have this alphabetic order: > levels(pH) [1] "alto" "baixo" "medio" the order by mean os yvar is: > sort(tapply(Riqueza,pH,mean)) baixo medio alto 11.56667 20.00000 26.80000 How to make the levels of pH ordered by this mean to the result to

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.

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) : there is no package

I've been struggling to get a loop to work. I want to create a new variable in each loop with data from some function. for example: # part of the names for the variables to be created Frags <- c("F04", "F05", "F07", "F09", "F11", "F13", "F14", "F17", "F18", "F19", "P20",

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: frame length

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: >

What sould be the capture and playback buffer size in 8,16,32 khz for the Alsa system? Can this also causing latency? In the server side I have: -A thread that reads the input from mic (capture) ands copies to main buffer. -The main loop encodes and sends it to the client ( it's read the data from the main buffer) Client: -A thread for

HI Utpal, Alight, I will look into it.? I was under the impression that this is what you wanted: dat1<- structure(list(V1 = c(1L, 1L, 1L, 1L, 1L, 1L, 1L), V2 = c(1L, 1L, 1L, 1L, 1L, 1L, 0L), V3 = c(1L, 1L, 1L, 1L, 1L, 1L, 1L), ??? V4 = c(1L, 1L, 0L, 1L, 1L, 1L, 1L), V5 = c(1L, 1L, 1L, 1L, ??? 1L, 0L, 1L), V6 = c(1L, 1L, 1L, 0L, 1L, 1L, 1L), V7 = c(1L, ??? 1L, 1L, 1L, 1L, 1L, 1L), V8 = c(1L,
