Re: [R] Read data from .csv file as a matrix and compare the different between two matrix
Hi, Not quite understand your question. Suppose the columns of one matrix (matrix1) have multiple 1's while matrix 2 have only 0's, do you mean that the difference should be 0 for that column? Anyway, the result that you wanted for this example can be got from: mat1-read.table(text= A B C 0 1 0 0 0 1 0 0 0 ,sep=,header=TRUE) mat2-read.table(text= A B C 0 1 0 0 0 0 0 0 0 ,sep=,header=TRUE) library(plyr) join(mat1,mat2,type=inner) # A B C #1 0 1 0 #2 0 0 0 #3 0 0 0 #This solution may not work in situations like the one I mentioned above.
