Hi All,I have a very simple problem: I have a table. How can I add the maximal value of each row in a new column to the table? (I tried "apply(table, 1, max)" but without success)ThanksBalazs __________________________________________________________ Dem pfiffigeren Posteingang. [[alternative HTML version deleted]]

For instance: > a <- matrix(1:100, nrow=10, ncol=10) > a [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [1,] 1 11 21 31 41 51 61 71 81 91 [2,] 2 12 22 32 42 52 62 72 82 92 [3,] 3 13 23 33 43 53 63 73 83 93 [4,] 4 14 24 34 44 54 64 74 84 94 [5,] 5 15 25 35 45 55 65 75 85 95 [6,] 6 16 26 36 46 56 66 76 86 96 [7,] 7 17 27 37 47 57 67 77 87 97 [8,] 8 18 28 38 48 58 68 78 88 98 [9,] 9 19 29 39 49 59 69 79 89 99 [10,] 10 20 30 40 50 60 70 80 90 100 > apply(a, 1, max) [1] 91 92 93 94 95 96 97 98 99 100 Is the problem that you don't know how to make a new column to your table, or ... ? -steve -- Steve Lianoglou Graduate Student: Physiology, Biophysics and Systems Biology Weill Cornell Medical College http://cbio.mskcc.org/~lianos
