I have a data vector as following: > z [1] 183.1370 201.9610 113.7250 140.7840 156.2750 42.1569 42.1569 42.1569 [9] 240.1960 308.4310 42.1569 42.1569 42.1569 42.1569 42.1569 42.1569 [17] 42.1569 42.1569 42.1569 42.1569 279.8040 42.1569 42.1569
when I sort, it gave me the right order > sort(z) [1] 42.1569 42.1569 42.1569 42.1569 42.1569 42.1569 42.1569 42.1569 [9] 42.1569 42.1569 42.1569 42.1569 42.1569 42.1569 42.1569 113.7250 [17] 140.7840 156.2750 183.1370 201.9610 240.1960 279.8040 308.4310 BUT when I use the order, the returned index is strange and not right. You can check the first 4 values. > order (z) [1] 6 7 8 11 12 13 14 15 16 17 18 19 20 22 23 3 4 5 1 2 9 21 10 I am not sure why R does not order it correctly when handling a vector with repetitive values. I use just the first 4 values of z, then it ordered correctly. > order (z[1:4]) [1] 3 4 1 2 Can someone help? What is the problem here? Is this a R bug?
