Thanks Peter, that got me there. I added this bit of code to make it count the number of rows that would be output for the reshape verb (since I don't know that from the outset).
I always end up using [: a lot when I write tacit programs. Out of interest, does anyone know a cleaner way to write the tacit expression below? ( (([: +/[: > [: #&.> ]),2:) $ [: ;[:; ]) (<10 20);<(3 4;<1 2) Cheers, Matthew. --- Peter Vingron <[EMAIL PROTECTED]> wrote: > Hallo Mathew, > > Is this of any help?: > > 3 2$;;(<10 20);<(3 4;< 1 2) > > regards, > Peter > > > Matthew Brand schrieb: > > Hi All, > > > > How can I get pairs of numbers which are in boxes > like > > this: > > (<10 20);<(3 4;< 1 2) > > > > out into an array that looks like this: > > 3 2 $ 10 20 3 4 1 2 > > > > The contents of each box are x,y data points that > I > > want to lump together and model. > > > > The number of levels/structure is always as in the > > example, that is a list of boxes where each box > > contains a list of boxes where the boxes contain a > > list of 2 numeric atoms. > > > > Thanks, > > Matthew. > > > > > > > __________________________________________________________ > > Sent from Yahoo!
