Possible Error in Definition

The article currently states, "If n is an integer and K is either the field of the real numbers or the field of the complex number, then K^n is naturally endowed with a structure of vector space, where K^n is the set of the ordered sequences of n elements of K." This seems to say that the set K can have a negative number of elements. — Preceding unsigned comment added by 76.16.195.106 (talk) 23:52, 26 November 2011 (UTC)[reply]

Ambiguous Disambiguation Page

This disambiguation page is confusing. The primary analogate of all these uses of "vector" is the mathematical "Euclidean vector." I'm a physicist who's never heard "vectors" called by a name that makes it sound like they don't exist in non-Euclidean geometries. Whatever the provenance of that name, it will be intuitively obvious to few people what that means, so people will putz around the page looking for the page on "vector" before clicking on a guess. I'm not sure what the solution is, but the current situation (with, e.g., so many links duplicated in the appropriate places in the "Euclidean vector" article) is just silly.

One of these people looking for the definition of vector as used in statistical programs like R. I was also only familiar with vector as used in physics (i.e. atribute with both value and direction) and could not figure out how to relate this to the vector data type in R. Not sure this page helped me at all. — Preceding unsigned comment added by 41.3.173.252 (talk) 11:02, 20 September 2011 (UTC)[reply]
