Hi everybody,

This has been causing me some trouble:

I want to combine several lists of pairs into a single?vector but keep the pairs together. The lists are of the form:
(1)?x1 x2 x3... N? 
(2) y1 y2 y3..? N

I would like to keep it this way, simply appending one list to another, e.g.
(1) x1i x2i... x1j x2j... N
(2) etc.

A?method like c(...) does not achieve this. It creates a single list, disregarding the pairs.

Is there a more efficient way of doing it?

Thanks!
Oliver Marshall
