But note that m:n does not always produce an integer sequence. It does when
the output can be accurately represented as an integer sequence, it
does not care
if the inputs were integer or numeric.

Hello,
Not an answer to the OP's statement, but

[1] "integer"

[1] "integer"
When using m:n there's no need for mL or nL.

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
