Hi, I have an array of dimension 6:6:160000. I want to stack the 160000 slices of the array into a matrix or a data frame of dimension 6:(6*160000=960000) in order to write it to a csv file. It seems I cannot get the matrix or data.frame functions to put the values from the array in the same order as they appear in the array easily, but I am almost sure there is an easy way to do this.
#Here is code for a small 6:6:2 array. x=rep(rep(1:6,each=6),2) dim(x)=c(6,6,2) x #Matrix approach 1: matrix(x,nrow=12,ncol=6,byrow=F) #Matrix approach 2: matrix(x,nrow=12,ncol=6,byrow=T) #Data frame approach (cbinds rather than rbinds): data.frame(x) None of the above works as I would like to. The "correct" approach should stack the same values all in the same column of the matrix or data frame. I also could not get "stack" to work correctly and would appreciate your help.
