the main thing missing in my nested list plan is a name for the atomt
type. it can't really be A_LIST because of this correspondence
atomtype - selector
A_FLOAT float
A_SYMBOLsymbol
A_POINTER pointer
but A_LIST can't work because the name list is already taken for a type
of non-atom message. (an atom message is one carries exactly one atom
which is always supposed to be of the type indicated by the selector)
I'm thinking of plist meaning pointer-to-list, or listp as list
pointer, because that'll be what it is. if you put this in a
messagebox:
{1 2 3}
it would be equivalent to writing it with that selector, e.g.:
listp {1 2 3}
and because that's an atomtype and that it would be able to contain the
same thing that a regular list-message can, you will be able to nest
listp into list or into listp:
1 2 3 {4 5 6}
is like
list 1 2 3 {4 5 6}
{1 2 3 {4 5 6}}
is like
listp 1 2 3 {4 5 6}
so, what do you think? is listp a good word? what else could it be?
(besides, another advantage of listp over regular lists is that they would
be more efficient because they would require less copying of memory)

For quantitative structure-property relationship models, that could be a
very good tool.
so, what do you think? is listp a good word?
I don't know if I could help to find the good answer because I'm rather
seducted by the word
E_STATE
for some reasons I would explain if it's really important,
which means electrotopological state.

Re: [PD] Multi dimensional [list]
A two-dimensional array data-type out of a list of floats with delimiter items to go with something like 2dtabread and 2dtabwrite abstractions. - Has anyone done that already? I've done something like that for storing parameters in arrays, but like matthieux bouchard said for matrixes, the length of the 'listed list' is fixed. An example with arrays is attached. I would be glad to make a version where the list lengthes are not fixed, but it's very complicated to do with arrays, [trigger], [once] and [until] maybe someone will find it out later...

I guess you will like the iemmatrix-externals. The difference between matrices and lists-of-lists is that, in the former case, the sublists need to be of fixed size. Well, yes, that's of course true, and if it's an issue for a certain application, then a more elaborate approach is needed. For example something like [pool] can be handy here. Just for illustrating how data structures could be used to build slightly more complex, uhm, data structures, I made a lists-of-lists in attached useless example patch.
