Henrique, Again, thank you very much for your code snippets, I am learning from them, but they are also creating as many questions as answers... On Sun, Mar 2, 2008 at 11:48 AM, Henrique Dallazuanna <[EMAIL PROTECTED]> wrote: > Then you can try this: > > apply(array(as.vector(sapply(patt, get)),

Then you can try this: apply(array(as.vector(sapply(patt, get)), dim = c(dim(get(patt[1])), ngroups, nsubs)), 1:3, mean) For create the matrices in a loop one option is: lapply(seq(1, 51, by=10), function(x)matrix(seq(x, x+8), nrow=3, ncol=3)) On 02/03/2008, Emilio Gagliardi <[EMAIL PROTECTE

One options is: data.1 <- matrix(seq(from=1,to=9,by=1),nrow=3,ncol=3) data.2 <- matrix(seq(from=11,to=19,by=1),nrow=3,ncol=3) data.3 <- matrix(seq(from=21,to=29,by=1),nrow=3,ncol=3) data.4 <- matrix(seq(from=31,to=39,by=1),nrow=3,ncol=3) data.5 <- matrix(seq(from=41,to=49,by=1),nrow=3,ncol=3) data

[R] summarizing matrix data

2008-03-02 Thread Emilio Gagliardi
Hi everyone, I'm sure this is simple, but I can't seem to figure this out. Situation. 3 different groups of subjects each submit n X n matrices of scores. What I want to do is aggregate each group of scores into a summary n X n matrix. I need the result to be a matrix so that I can calculate a
