I haven't seen very many flames -- there have been disagreements, but
generally it's been quite civil. Certainly I don't think Berwin flamed me.
If we were to add in a warning about partial name matching, it would
have to be accompanied by some way to deal with common uses like the one
Berwin mentioned. (There are at least 100 uses of seq(..., length=...)
in the core & recommended packages. I wouldn't want to fix all of
those.) But it could still be useful, in the same way the checks for
using TRUE and FALSE instead of T and F are useful.

I think this tension is a fundamental part of the character of S and

to improve reliability. [...]
Please not. :)
After years of using of R, it is now second nature to me to type (yes,
I always spell out "from" and "to")
seq(from=xx, to=yy, length=zz)
and I never understood why the full name of that argument had to be
length.out. I would hate to see lots of warning messages because I am
using partial matching.
