Hi all, I'm trying to use heat.map to display some data. The data is originally in csv format and when I read it in R using read.table I get: a b c d e 1 A 1 1 1 1 2 B 1 0 1 1 3 C 0 1 0 1 4 D 1 1 1 0 5 E 1 0 0 0 The problem is, that for heatmap I need a numerical matrix. When using data.matrix I get: a b c d e [1,] 1 1 1 1 1 [2,] 2 1 0 1 1 [3,] 3 0 1 0 1 [4,] 4 1 1 1 0 [5,] 5 1 0 0 0 So I get numerical... but I loss the row names. I would like to see these names as the y axis labels. What is the correct/easiest way of achieving this? Many thanks!!! -- View this message in context: http://n4.nabble.com/heatmap-image-from-csv-data-tp956968p956968.html Sent from the R help mailing list archive at Nabble.com.
