estimate value from simulations
Hello, Try the following. mat <- matrix(scan(text = " 1 1 1 1 1 1 2 2 2 2 2 2 3 3 3 3 3 3 5 5 5 5 5 5 2 2 2 2 2 2 3 3 3 3 3 3 6 6 6 6 6 6 2 2 2 2 2 2 3 3 3 3 3 3 1 1 1 1 1 1 2 2 2 2 2 2 3 3 3 3 3 3 "), ncol = 6, byrow = TRUE) idx <- 1 + (seq_len(nrow(mat)) - 1) %% 3 aggregate(mat, list(idx), mean) Hope this helps, Rui Barradas Em 16-05-2013 07:17, Zilefac Elvis escreveu:
Hello, I need your help on this matrix: 1 1 1 1 1 1 2 2 2 2 2 2 3 3 3 3 3 3 5 5 5 5 5 5 2 2 2 2 2 2 3 3 3 3 3 3 6 6 6 6 6 6 2 2 2 2 2 2 3 3 3 3 3 3 1 1 1 1 1 1 2 2 2 2 2 2 3 3 3 3 3 3 First three rows represent first simulation, next three rows = second simulation etc. I would like to estimate the values in row 1 for example by taking the mean of rows 1, 4, 7, 10. Do same for all other rows. So the resulting matrix is 3-by-6. Thanks Atem. [[alternative HTML version deleted]]
