[R] reorder data.frame

[Johannes Radinger]

Hello,

I very general question but probably usefull to others as well:

Is there any prebuild function that reorders a dataframe from:

   x1    x2
1  100   200
2  101   201
3  102   202
4  103   203
5  104   204
6  105   205

to

1  100  x1
2  101  x1
3  102  x1
4  103  x1
5  104  x1
6  105  x1
7  200  x2
8  201  x2
9  202  x2
10  203  x2
11  204  x2
12  205  x2

I found a way with:

names <- rep(c("x1","x2"),c(length(x1),length(x2)))
x <-c(x1,x2)
data.frame(x,names)

but probably there is already another function for doing such things more easily.

Thank you
Johannes
