Why is the rows-indicies effected by ordering?
Those are row names, not row indices.
Example: (data=) name age 1 peter 13 2 eric 15 3 daniel 14 #ordering by name... name age 3 daniel 14 2 eric 15 1 peter 13 why not: name age 1 daniel 14 2 eric 15 3 peter 13 Does it effect other operations? data[,1] really gives the 1:st row, but when data is printed it says that the first row have index 3...
*row name* 3. Indices are printed like [3,] as in
matrix(1:9, 3)
[,1] [,2] [,3] [1,] 1 4 7 [2,] 2 5 8 [3,] 3 6 9 Try a data frame like swiss with real names (in 1.3.0) rather than names which happen to be 1:nrow(df).
