After just a little more thought let me answer my own question.
a. The as.vector() function is designed to strip off everything extraneous and
leave just
the core. (I have a mental image of Jack Webb saying "Just the facts ma'am").
I myself
use it freqently in the test suite for survival, in cases where I'm checking
the corrent
numeric result and don't care about any attached names.
b. is.vector(x) essentially answers the question "does x look like a result
of as.vector?"
Nevertheless I understand Roger's confusion.
