No that is not a bug. You are confusing order() with sort(). Please do read
the helpfiles.

To call in the statistician after the experiment is done may be no more than
asking him to perform a post-mortem examination: he may be able to say what
the experiment died of. ~ Sir Ronald Aylmer Fisher The plural of anecdote is
not data. ~ Roger Brinner The combination of some data and an aching desire
for an answer does not ensure that a reasonable answer can be extracted from
a given body of data. ~ John Tukey

Onderwerp: [R] the bug of function base::order
Hi, all:
I find a bug of the function base::order. For example,
y = rep(9, 9:1); rbind(y,order(y, decreasing=FALSE));
the result is:
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10]
y 9 9 8 7 6 5 4 3 2 1
10 9 8 7 6 5 4 3 1 2
The last two numbers have the wrong orders!
Is there any one met the same situation?
