Hello, There are several notions of equal. Note that all(mat1 == mat2) alone doesn't allways do it, it only works if the matrices have equal dimensions. If they don't, it breaks the code. That's the case of the first example below. Try the following. a - matrix(1:16, ncol=2) b -

[R] compare two matrices

Hi everyone: I have a kinda easy question but i do not know how to solve that in a simple way. I want to compare the rows of two matrices. col1 - c(1,2,3,4,5,6) col2 - c(6,5,4,3,2,1) m - cbind(col1, col2) col3 - c(1,3,2,6) col4 - c(6,3,5,1) n - cbind(col3,

Re: [R] compare two matrices

one way is the following: col1 - c(1,2,3,4,5,6) col2 - c(6,5,4,3,2,1) m - cbind(col1, col2) col3 - c(1,3,2,6) col4 - c(6,3,5,1) n - cbind(col3, col4) ind.n - do.call(paste, c(as.data.frame(n), sep = \r)) ind.m - do.call(paste, c(as.data.frame(m), sep = \r)) ind.n %in% ind.m I hope it helps.
