Hello, I have some trouble using step() and stepAIC() functions. I'm predicting recruitment against several factors for different plant species using a negative binomial glm. Sometimes, summary(step(model)) or summary(stepAIC(model) does not select the best model (lowest AIC) but just stops before. For some species, step() works and stepAIC don't and in others, it's the opposite.

Hello, I have some "stupid" problems managing "date" data. I have a colomn "date", which I converted from a character representation: for example: a="26/02/06" date=strptime(a,format="%d/%m/%y") For one part of the analysis, I'm interested only in the month and the year, so I did: m.y=strftime(date,format="%m/%y") This returns me

Hi, I bought a Digium Quad E1 card model TE406P. Till now, I can't make it work... I mean, I have red alarm when I configure one E1.

Hello, I have problems using the functions as.Date and strptime/strftime of base package and some functions of package zoo in my computer (Apple, Mac OS X 10.3.9). When I use them, the R application closes... However, it depends on the length of the vector I want to transform. For example, in the data.frame: climat[c(1:5,1460:1462),] date TEMP_STG PRECIP_STG 1 01/01/01

Dear all, I'm using R version 3.2.0 in Ubuntu 12.04 LTS. While trying to install any package I get the error: "/usr/bin/ld: cannot find -lgfortran" If I open a Terminal and run "ldconfig -p | grep libgfortran"?, I get:? "libgfortran.so.3 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libgfortran.so.3" I've been an R user for two years and this is the

Hi, I am Olga Viedma. I am running a Zero-inflated negative binomial (ZINB) multi-level model using MCMCglmm package. I have a doubt. Can I use the "Liab" outputs as fitted data, instead of the predicted values from "predict"? The liab outputs fit very well with the observed data, whereas the predicted values are so bad. Thanks in advance, Olga Viedma D . Olga

Hello, I use lme4 package. library(lme4) fit=lmer(y ~ time+dye+trt+trt:time + (1|rep), data=dataset, na.action='na.omit') anova(fit) The anova gives sequential F-tests and sequential SS. My question is: how I can get partial F-tests and partial SS? For lm (not lmer) anova(lm(y~x+z)) we can use anova(fit, ssType=3) but it is not work for lmer. Natalia.

Hola! Quiero empezar a georeferenciar en mapas con R. En blogs se encuentra bastante información pero veo que no hay unanimidad respecto a las librerías a utilizar ni tampoco la información es muy clara ni abarcativa. ¿Alguno/a trabaja con mapas en R y me puede indicar por donde encarar? En principio mi interés es realizar mapas sencillos con información por provincias y departamentos de

Hello all, is there any recent information on programming on how to add a new authentication method into OpenSSH / OpenSSL ?! Is there any other way, to add a new authentication method into openssh (one-time passwords), apart from adding the functions into sshconnect.c and sshconnect2.c Particularly I'm interested in information on "struct Authctxt" in sshconnect2 and sshuserauth2.

Hello all, I have problem with setting up random effects. I have a model: y=x1+x2+x1*x2+z1+z1*x2 where x1, x2, x1*x2 are fixed effects and z1, z1*x2 are random effects (crossed effects) I use library(nlme) 'lme' function. My question is: how I should set up random effects? I did lme(y~x1+x2+x1:x2, data=DATA, random=~z1+z1:x2, na.action='na.omit') but it did not work.

I am hoping to create a graph that will look like it is plotted on arithmetic probability plot. Something similar to how this is done in Excel: http://peltiertech.com/Excel/Charts/ProbabilityChart.html. I can't quite find a code that will transform the linear axis into a cumulative percent axis with an arithmetic probability. And I am not good enough at R to do that myself. Any help will be

Dear all, I've been reading for many days trying to predict with lmer but I haven't managed to do it. I've fitted an allometric model for trees where I have included climatic variables and diameter in the fixed part and in the random part I've included the experimental sites where trees are and also their provenance region. The model is like this :
