useR's, I have several matrices of size 4x4 that I want to calculate means of their respective positions with. For example, consider I have 3 matrices given by the code: mat1 <- matrix(sample(1:20,16,replace=T),4,4) mat2 <- matrix(sample(-5:15,16,replace=T),4,4) mat3 <- matrix(sample(5:25,16,replace=T),4,4)
The result I want is one matrix of size 4x4 in which position [1,1] is the mean of position [1,1] of the given three matrices. The same goes for all other positions of the matrix. If these three matrices are given in separate text files, how can I write code that will get this result I need?
