Hello, I was using version 2.13.2 and I have just downloaded the latest version 2.14.1. However, I''m trying to install the packages I was using and when I look for them in the packages list, I can´t find many in the CRAN binaries (e.g. "vegan"). I do find them in the CRAN sources but the installation fails. I tried downloading the version 2.14.0 and I had the same problem. I

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

Hello, I am using function lmodel2 to calculate RMA regression between life-history traits in ladybirds beetles. It works well but I am not able to plot an RMA regression line on the scatterplot of my data. I am of course unable to plot the confidence intervals. For ordinary least square regression abline(lm(x~y))works well but for RMA regression, abline(lmodel2(x~y))does not do it. If somebody

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

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.

Hi List, I'm trying to built a list where there are some missing data in some columns, then I would like to know what I should put in these blank spaces when building the vector. eg: color<- c("red",?,"orange","green",?,?,?) size<- c(2,1,?,3,?,?,8) Thanks, Natalia [[alternative HTML version deleted]]

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 :

Hi, I’m sorry, I know that it is a recurrent question but I have not been able to find the response in the Rhelp archives. I think my data require the use of the glmmPQL function but I do not know how to make the model selection. Since the AIC and log-likelihood are apparently meaningless, how can we select the parameters for a model and compare the models to find which one fits best the data?

Hi! I'm trying to run logistic regression on a dataset which is contained in dataframe "data" ("y" is in the first col, and 28 parameters for the model). How can I write formula for function `glm` without listing explicitly all 28 paramaters? `glm(data[,1]~data[,2]+data[,3]+data[,4]+...,family=binomial)` As an option I can use `glm.fit(data[,-1],data[,1],family =

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.

Hi everyone! I would appreciate help with using decompose.graph(), community detection functions from igraph and lapply(). I have an igraph object G with vertex attribute "label" and edge attribute "weight". I want to calculate community memberships using different functions from igraph, for simplicity let it be "walktrap.community". This graph is not connected,

Hi I have folowed this guide http://www.enterprisenetworkingplanet.com/netos/article.php/3457461 to import users from my NT4 domain to a debian sarge with samba 3.0.14a Everything runs fine till the net rpc vampire command, some users give an error others are imported fine. I don't see any problem on this users configuration in the NT4 server, here is part of the output: thanks.

Hi All, When I tried to do logistic regression (with high maximum number of iterations) I got the following warning message Warning message: fitted probabilities numerically 0 or 1 occurred in: (if (is.empty.model(mt)) glm.fit.null else glm.fit)(x = X, y = Y, As I checked from the Archive R-Help mails, it seems that this happens when the dataset exhibits complete separation. However, p-values
