Re: [R] Fetching a range of columns

David, Using the ?count.fields revealed that I only have 2410 columns. That fixed the problem I had. I used, data_tmp[,842:2410] and that gave me the solution I was looking for. This, ironically, also solved the other problem I had. As for: > > You also say file.remove( fileout) , then you try

Re: [R] Ward's Clustering Doubts

Hi Rodrigo, [apropos of Ward's method] >> ... we saw something like "You must use it with Euclidean Distance..." Strictly speaking this is probably correct, as Ward's method does an analysis of variance type of decomposition and so doesn't really make much sense (I think) unless Euclidean dist

Re: [R] How to draw a plot like this?

I think the function split.screen() in 'graphics' package is enough for this task. For example, ## fig.loc = matrix(c(0, 1, 0, 1, 0.1, 0.6, 0.5, 0.9), 2, byrow = T) x = split.screen(fig.loc) par(mar = c(3, 3, 1, 1)) screen(1) plot(rnorm(100)) screen(2) plot(rnorm(20), type = "h") Yihui On Mo

Re: [R] Help please! How to code a mixed-model with 2 within-subject factors using lme or lmer?

Hi Roberto, The other thing you can do --- if you don't wish to step across to lmer(), where you will be able to exactly replicate the crossed-factor error structure --- is stay with aov(... + Error()), but fit the factor you are interested in last. Assume it is Sex. Then fit your model as aov.m

Dear useRs, What is an efficient way to randomly sample from clustered data such that I get equal representation from each cluster? For example, let's say I want to randomly sample two cases from each cluster created by the "id" variable in the following data frame: > id<-c(rep("100", 4),re
