I think that "length" (in the R way) or "size" should
incorporate the
number of columns (or other dimension information).
How about:> vec_npoints (x)
> vec_nrecords (x)
> vec_nobs (x)
Depending on whether you want to promote geometry, databases or statistics.
I like npoints because I like to be Geometry-Friendly :).
This next issue isn't probably the feedback you're looking for.
However, given that you brought it up...

This is very interesting.
I'm writing a function where I'm planning to do the complete opposite.
I could return the number of lines of a function or the number of it's
arguments.
However, it would be nice to do something like.
> object.size (mean)
f: Nn -> N1
(Note that I'm using "N" for numeric rather than the more obvious
"R" for real).
It's difficult for an R function to determine the input types of
another R function and even more difficult to determine the output
types.
It may be possible to incorporate a comment as a variable (inside a
function) rather than a comment as a comment.
> mymean = function (x)
+ { #info
+ .map = "f: Nn -> N1"
+
+ mean (x)
+ }
kind regards
