Hi, I have 2 questions on list object: 1. Suppose I have a matrix like: dat <- matrix(1:9,3) Now I want to replicate this entire matrix 3 times and put entire result in a list object. Means, if "res" is the resulting list then I should have: res[[1]]=dat, res[[2]]=dat, res[[3]]=dat How can I do that in the easilest manner? 2. Suppose I have 2 list objects: list1 <- list2 <- vector("list", length=2) for(i in 1:2) { list1[[i]] <- matrix(rnorm(15), 3) list2[[i]] <- matrix(rnorm(15), 3) }
How can I add these 2 list objects? I have tried with just list1+list2, however it is generating some error. Would be grateful for any help. Thanks, [[alternative HTML version deleted]]
