Hello, I'm creating a loop to work with vegan, to get a species abundance curve. Here I send the script I've created and also an excel file to prove what it can do. Well, I have a database with 20 years, and each year we have sampled 19 stratum, and in each estratum we have carry out some sumpling. Then, with the script that I've sent I've got to calculate the species abundance

Hi, Is it possible to place the group number in a cluster? The best example I found was at https://www.crops.org/images/publications/cs/42/5/1584f4.jpeg (see I, II, IIIa, IIIb) It would help to identify the group given by cutree since branches can turn around and they necessarily are not plotted in order (group 2 is not necessarily the second from the left). Thanks for any help. All the

Dear list members I have a doubt on how p-values for t-statistics are calculated in the summary of Linear Models. Here goes an example: x <- rnorm(100,50,10) y <- rnorm(100,0,5) fit1<-lm(y~x) summary(fit1) summary(fit1)$coef[2] # b summary(fit1)$coef[4] # Std. Error summary(fit1)$coef[6] # t-statistic summary(fit1)$coef[8] # Pr(>|t| summary(fit1)$df [2] # degrees of freedom #

This works fine: fit42<-nls(Vfs~SSlogis(Months,Asym.Int+Asym.Group*Groupdum,xmid,scal), data=df, start=c(Asym.Int=22,Asym.Group=5,xmid=2,scal=6), na.action=na.omit) But this, identical except using gnls, doesn't converge: fit43<-gnls(Vfs~SSlogis(Months,Asym.Int+Asym.Group*Groupdum,xmid,scal), data=df, start=c(Asym.Int=22,Asym.Group=5,xmid=2,scal=6), na.action=na.omit) Error in gnls(Vfs

Dear all, I am trying to generate bootstrap replicate matrixes (rows=samples, column=species, sampling with replacement) from a matrix dataset, but I do not know how to do it in R. I have tried boot() and bootstrap(), but they require an statistic, which in my case is cluster analysis (generating bootstrap values for a cluster analysis is a topic that has been mentioned previously in

...aso, el mar queda a unos 700 km en línea recta desde mi casa, y el Báltico a miles de km, entenderá mi ignorancia al respecto, pero de esto salen algunas preguntas que son muy básicas, casi de ignorante, en primer lugar para tener embriones hacen falta adultos, ¿hay registros de estos?¿donde están?¿pesca?. Mi segunda pregunta es, por ejemplo en el patio de mi casa hay una parra y siempre vienen palomas y hacen su nido en dos o tres lugares que se repiten todos los años, por lo cual el encontrar huevos está espacialmente relacionado al nido de arriba, ¿hay algún tipo de ubicación reproductiva?

Hi all, After running kruskal.test I have got results (p<0,005) pointing to reject the hypothesis that the samples were draw from the same population. Howerver when I run the kruskalmc there are no significant differences in any of the multiple comparisons. Is that possible? Some clarification?

Estimado Javier, Gracias por tus comentarios. Si, puede ser que me haya expresado en forma incorrecta. Mi idea fue tratar de ser lo mas conciso posible y limitarme al problema estadistico que tengo, por lo cual obvie mucha informacion. La data proviene de un monitoreo que se hace en el Mar Baltico anulamente hace mas de 20 años, debido a que la poblacion a decendido drasticamente en los
