i'm somehow embarrassed to even ask this, but is there any built-in method for doing this:
my_list <- list() my_list[[1]] <- matrix(1:20, ncol = 5) my_list[[2]] <- matrix(20:1, ncol = 5) now, knowing that these matrices are identical in dimension, i'd like to unfold the list to a 2x4x5 (or some other permutation of the dim sizes) array. i know i can initialize the array, then loop through my_list to fill the array, but somehow this seems inelegant. i also know i can vectorize the matrices and unlist the list, then build the array from that single vector, but this also seems inelegant (and an easy place to introduce errors/bugs). i can't seem to find any built-in that handles this already... but maybe i just haven't looked hard enough :-/ cheers, -m ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
