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 <- matrix(

Dear Members, I have two estimated transition matrices and I want to compare them. In fact I want to check the hypothesis if they come from the same process. I tried to look for some test but all I found was independence test of contingency tables. The following code shows that the usual chi-squ

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

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(col
