Say I have: > set.seed( 1 ) > m <- matrix( runif(5^2), nrow=5, dimnames = list( c("A","B","C","D","E"), > c("O","P","Q","R","S") ) ) > m O P Q R S A 0.2655087 0.89838968 0.2059746 0.4976992 0.9347052 B 0.3721239 0.94467527 0.1765568 0.7176185 0.2121425 C 0.5728534 0.66079779 0.6870228 0.9919061 0.6516738 D 0.9082078 0.62911404 0.3841037 0.3800352 0.1255551 E 0.2016819 0.06178627 0.7698414 0.7774452 0.2672207
------------------------------------------------------------------------------------------- I want to create a vector v from matrix m that looks like this: A.O 0.2655087 B.O 0.3721239 v <- as.vector( m ) almost gives me what I want, but then I need to take combinations of colnames( m ) and rownames( m ) to get my labels and hope they match up in order: if not, manipulate the order. This approach feels kludgy... Is this the right approach or is there a better way? -- View this message in context: http://www.nabble.com/Converting-a-Matrix-to-a-Vector-tp22696267p22696267.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.
