Hi, I have two table matrix, and I would like to compare the different between two matrix. For example:
Matrix 1: A B C A 0 1 0 B 0 0 1 C 0 0 0 Matrix 2: A B C A 0 1 0 B 0 0 0 C 0 0 0 Each column which have value 1, should also return value 1. As in this case/example, the result should appear like this (as below). The result of this differentiation should also be in matrix table and should be write in . csv file. Result of the differences: A B C A 0 1 0 B 0 0 0 C 0 0 0 At the mean time, I'm able to load the .csv file and convert it to matrix matrix1 <-read.table("matrix1.csv", header=T, sep=",") matrix1 <- as.matrix(matrix1) matrix2 <- read.table("matrix2.csv", header=T, sep=",") matrix2 <- as.matrix(matrix2) But, I can't find a suitable script to compare the differences between the matrix and write it to file.
