Hi All,
Suppose I have data like
b[[1]] = matrix(1:4, 2, 2)
b[[2]] = matrix(10:13, 2, 2)
b[[3]] = matrix(20:23, 2, 2)
[[1]]
[,1] [,2]
[1,] 1 3
[2,] 2 4
[[2]]
[,1] [,2]
[1,] 10 12
[2,] 11 13
[[3]]
[,1] [,2]
[1,] 20 22
[2,] 21 23
Now I want to calculate the mean of each cell across the list.
For example mean of (b[[1]][1,1], b[[2]][1,1], b[[3]][1,1]), mean of
(b[[1]][1,2], b[[2]][1,2], b[[3]][1,2]) etc. e.g. mean of (1, 10, 20), mean
of(3, 12, 22). Could somebody tell me how to do it? Thank you in advance.
