Hello R-users, I have a little problem.
I compare each row of a matrix with each row of another matrix. testmat1 <- matrix(c(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16), nrow=4) testmat2 <- matrix(c(1,2,3,5,5,6,7,8,9,10,11,12,13,14,15,16), nrow=4) Both matrix differs in the last row. Now I create a loop: for (i in (1:4)){ for (j in (1:4)){ b <- (c(setequal(testmat1[j,],testmat2[i,]))) print(b) } } R outputs me the following: [1] TRUE [1] FALSE [1] FALSE [1] FALSE [1] FALSE [1] TRUE [1] FALSE [1] FALSE [1] FALSE [1] FALSE [1] TRUE [1] FALSE [1] FALSE [1] FALSE [1] FALSE [1] FALSE but I need one vector like this: [1] TRUE FALSE FALSE FALSE FALSE TRUE FALSE FALSE FALSE FALSE TRUE FALSE FALSE FALSE FALSE FALSE Any ideas? thanks -- View this message in context: http://www.nabble.com/Make-one-vector-from-matrix-comparison-tp20421761p20421761.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
