Hello,
I'm declaring vectors from R? by a macro:
r3vect(x) := for i in x do i :: [ i[1], i[2], i[3] ];
This works mostly. It does not work for r3vect([x]):
part: invalid index of list or matrix.
A vector named ?x? can not be declared this way. Why is this?
After ?r3vect([a]);? a is a vector: [a?, a?, a?], but the elements can
not be declared real:
(%i5) declare(a[1], real);
declare: improper argument: a?
Is there another (better) way to declare vectors from R??
MfG
bmg
