lmer and grouping fators
Hi, I make this model using lme m.lme <- lme(Glycogen~Treatment,random=~1|rTrt/Liver) How to make this using lmer? I try > m.lmer <- lmer(Glycogen~Treatment+(1|rTrt/Liver)) Erro em lmer(Glycogen ~ Treatment + (1 | rTrt/Liver)) : entry 0 in matrix[0,0] has row 2147483647 and column 2147483647 Al??m disso: Mensagem de aviso: / not meaningful for factors in: Ops.factor(rTrt, Liver)

[LLVMdev] Integer factorizations in clang
Hello, I have a small test case : a = b * c + b * d and clang is fatorizing b to get only one multiplication (-O3) which is normally good for most architectures. But in my case, that pattern takes just one instruction and I would like to recover it as is. Where can I find this particular optimization in clang ? Is there a way of setting multiplications as being cheaper t...

unbalanced design
Hi all, I'm new to R and have the following problem: I have a 2 factor design (a has 2 levels, b has 3 levels). I have an object kidney.aov which is an aov(y ~ a*b), and when I ask for model.tables(kidney.avo, se=T) I get the following message along with the table of effects: Design is unbalanced - use se.contrast() for se's but the design is NOT unbalanced... each fator level

Avoiding Biplot Labels Overllaping
Hi everybody, I'm trying, without success, to avoid some variables labels to overlap on a capscale (vegan package) object graph. I was able to move the labels with the coding below, but it moves the entire vector... CAPobj<-CAPpotiFT for(i in c(2:8))CAPobj$CCA[[i]][,1]<-CAPpotiFTI$CCA[[i]][,1] CAPpotiFTI$CCA[[i]][,1][2]<-0.85 And here the graphic script

Symbols on a capscale object plot
Hi, I'm a beginner with R, but I'm getting excellent results with it. Well I've got an capscale object (vegan package) and I want to made a biplot with symbols representing six groups of areas. With the plot.cca function and some par attributes (like 'labels') I was able to substitute the samples names for keyboard symbols ('x','o','#',ect), but it's

Using deriv3() in a separated nonlinear regression model
Hi all, I'm adjusting a nonlinear regression model for data that has a categorigal variable present. So, I can use nls() to do this considering the categorical variable, like this #------------------------------------------------------------ da <- expand.grid(tr=gl(2,1,la=c("tr")), x=1:12) da$y <- 10*da$x/(3+da$x)+rnorm(da$x,0,0.1) plot(y~x, da) n0 <-
