If your matrix is 'mat': apply(mat, 1, min) Example: > mat <- matrix(rnorm(30), ncol = 3) > mat [,1] [,2] [,3] [1,] -0.18136616 0.39529877 -1.4816285 [2,] 0.05523284 -0.52171745 0.4893621 [3,] -0.27029731 -0.86745328 -0.1918832 [4,] -0.73901526 -0.35762159 1.2695002 [5,] -0.11800851 -1.48057601 -0.8918780 [6,] -1.52627381 1.30498318 1.0749069 [7,] 0.08733351 1.17986453 -0.8514364 [8,] 0.02248721 0.03496345 -1.0305299 [9,] 0.72882492 1.32881042 -0.6423467 [10,] -0.20463172 -1.33260851 1.2732504 > apply(mat, 1, min) [1] -1.4816285 -0.5217175 -0.8674533 -0.7390153 -1.4805760 -1.5262738 [7] -0.8514364 -1.0305299 -0.6423467 -1.3326085 See ?apply for more information HTH, Marc Schwartz ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
