One way to do it is to use the 'abind' package > NCurvas <- 10 > NumSim <- 15 > dW <- replicate(NumSim, matrix(rnorm(NCurvas * 3), NCurvas, 3), + simplify = FALSE) > library(abind) > DW <- do.call(abind, c(dW, rev.along = 0)) > dim(DW) [1] 10 3 15
-----Original Message----- From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On Behalf Of Luis Felipe Parra Sent: Monday, 28 February 2011 10:59 AM To: r-help Subject: [R] Transforming list into an array Hello. I have the following object which is a list of length NumSim with each entry being a matrix of dimensions Ncurvas x 3: dW = replicate(NumSim,cbind(rnorm(Ncurvas),rnorm(Ncurvas),rnorm(Ncurvas)),simplify=F) I would like to transform it into an array of dimension Ncurvas x 3 x NumSim. Does anybody does how to do this? or how to generate directly and array composed of independent random nomrmal numbers of dimensions Ncurvas x 3 x NumSim.
