Hello, I want to compare mean trip duration (length.in.hours) across treatment conditions and colonies. I have 3 colonies and 2 treatments. So, one half of a colony gets a DWV treatment and the other half a control treatment...

Dear R experts This probably seems very easy to you guys, but I'm a beginner and would be really glad if someone helped me with this: I am trying to automate the execution of an R script (let's...

I'm trying to perform a RDA analysis in the vegan package using the "varpart" function. I have a matrix of community structure data in different sites (rows), which I want to explain using 3 matrices of environmental data. The...

Dear All, I wonder if anyone can please offer any advice on a model including 2 fixed effects and 1 random effect, as well as a covariate? The experimental design is as follows: I have a two by two factor...

Dear all, I have a dataset with a MLPA analysis of 4-daily (0, 4, 8, 12, 16) sets of samples of 20 individuals per treatment (control and DWV). I want to test how the proportion of infected bees changed...

I appreciate your help a lot. Unfortunately, none of your recommendations work. I have written a small program to illustrate my problems. I hope there is a solution... Cross1 <- data.frame(i=c(1,2,3),Y=c(3,2...

Hi, I'm simulating a Markov chain in Fortran interfaced with R-2.2.1 in order to generate data according to a Markov Random Field called the Potts model. R Version: platform i686-pc-linux-gnu arch i686 os...

Thank you for the answer. However, I sought in Doc. Writing R extensions, in particular in the paragraph 5.6 "Calling C from FORTRAN and vice versa" (page 67) but I did not find anything which could help me to...

Dear all, I am trying to compute repeatability estimates for proportion/count data (intra-class correlation coefficients ICC) following Nakagawa & Schielzeth (2010) on agressive mimicry data from reef fish. My data: I observed 19 tagged fish directly on a reef...

Hello Tom, Thanks for the reply. Unfortunately I do have many NAs in my data as not all vertical temperature profiles penetrated to the same depth level. In fact if I simply use na.omit my data matrix is reduced...

Hi Paul, Thank you very much for the hint! The treatment:colony term is not significant, so I will not include it in the model. However, I get the same results for the Tukey posthoc test as I had before...

Hi folks, I have a question concerning the output of a multilevel model in nlme, which I want to test for mediation with a monte carlo simulation (using the r-code generator at http://www.quantpsy.org/medmc/medmc111.htm...
