Hello,
Not an answer to the OP's statement, but
> class(1L:40000L)
[1] "integer"
> class(1:40000)
[1] "integer"
When using m:n there's no need for mL or nL.

Care to demonstrate for us, Karl?

You are wrong. No reordering occurs.

Dear all:
I have two data.frames A and B of the same number of rows (about
40,000). I
realized that when I copy column x from data.frame A to B, the order
of this
column gets changed. This seems to affect only values in rownumbers > ~
35/36,000. It also happens in any of the following three approaches:
A$x <- B$x
x <- B$x (here, x is still in the correct order)
B$x <- x : now x is reordered
B <- cbind(A, B$x)
I am working with Windows7Pro/64bit, R 3.3.3, and RStudio 0.99.903.
Any help would be appreciated.
Best regards
Karl Schilling
