fix() changes the class of mts objects
Why did you expect otherwise?: fix() is treating it as matrix and ?edit.matrix says that it only works on 'simple data frames' (and converts matrices to such). Editing R objects can easily change aspects of them, as dput() is not faithful, environments can get lost and so on.

Dear all, it looks like fix() changes the class of mts objects, here is a reproducible example (tested both on WinXP and Linux):
x <- ts(cbind(1:5,1:5)) x
Time Series: Start = 1 End = 5 Frequency = 1 Series 1 Series 2 1 1 1 2 2 2 3 3 3 4 4 4 5 5 5
class(x)
[1] "mts" "ts"
edit(x)
Series 1 Series 2 [1,] 1 1 [2,] 2 2 [3,] 3 3 [4,] 4 4 [5,] 5 5
class(x)
[1] "mts" "ts"
fix(x) class(x)
[1] "matrix"
x
Series 1 Series 2 [1,] 1 1 [2,] 2 2 [3,] 3 3 [4,] 4 4 [5,] 5 5
