R-gurus... I've got a 5 column dataframe where I'd like to plot each ID's "b" against "c" with "b" in ascending order (within the same ID). How do I sort "b" so that the other variables are altered equally? ID a b c d 101 1 240 26.7 21.85 101 2 335 21.8 21.85 101 3 1387 26.6 21.85 101 4 877 24.1 21.85 101 5 978 24.3 21.85 101 7 4962 28.3 21.85 101 8 1690 26.1 21.85 101 9 2038 24.4 21.85 102 1 240 53.4 51.65 102 2 533 50.4 51.65 102 3 802 53.3 51.65 102 4 1155 47.0 51.65 102 5 953 47.7 51.65 102 7 5353 47.8 51.65 . . . 115 9 840 34.9 42.01 All the best, Kare
