Hi, I would like to sort a data frame by a column, the column to sort by has a list of numbers 1:150 (a few numbers are missing so the total is 137) and two letters "S" , "Z". How can I sort it so that first I have the numbers in running order (1,2,3,...150) and then the letters S and Z?
the column class is "factor" [1] 1 10 100 101 102 104 105 106 107 108 109 11 110 111 113 114 115 116 [19] 117 118 119 12 120 122 123 124 125 126 127 128 129 130 131 132 134 135 [37] 136 137 138 139 140 141 142 143 144 145 146 147 148 149 15 150 16 17 [55] 18 19 2 20 22 23 24 25 26 27 28 29 3 30 31 32 33 34 [73] 35 36 37 38 39 4 40 41 42 43 44 45 46 47 48 5 50 51 [91] 52 53 54 55 56 57 58 59 6 60 61 62 63 64 65 68 69 7 [109] 70 71 72 74 76 77 78 79 8 80 81 82 83 84 85 86 87 88 [127] 89 9 90 91 92 93 94 95 96 97 98 S Z Thanks, Raz -- \m/ [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
