decrease list of lists by 1 hierarchy list

Leonardo Vinci over 7 years ago

i have a list named A in this format: ( (((x1) (y1))) (((x2)(y2))) (((x3)(y3))) )

But i have to decrease its listing hierarchy by 1, ie. i want a format like this: ( ((x1)(y1)) ((x2)(y2)) ((x3)(y3)) )

How can i do this?

Thanks,

Leonardo da Vinci

You can do this (destructively) by doing:

A=foreach(mapcan sublist A sublist)

You can do it non-destructively (if each sublist only has a single element) by doing:

foreach(mapcar sublist A car(sublist))

Regards,

Andrew.
