Hi Evan,
You may find some parts of what we are doing with genthat useful. Genthat is a
tool
for creating unit tests by recording argument and return values of calls. This
is
done by instrumentation of the source code.
The git repo with the code is here https://github.com/PRL-PRG/genthat

Does anyone know why logical vectors are *silently* recycled, even

Hi Tomas,
Thanks for your reply.
I find your response curious, however. Surely the identical() test is
simply incorrect when catering for possibly different BLAS
implementations? Or is it the case that conformant BLAS implementations
all produce bit-identical results, which seems unlikely? (So
One use case is when you want to extract every third item, starting with
the second, of an arbitrary vector with
x[c(FALSE, TRUE, FALSE)]
instead of
x[seq_along(x) %% 3 == 2]

It is convenient to use a s
Hmm.
Chuck: I don't see how this example represents
incomplete/incommensurate recycling. Doesn't TRUE replicate from
length-1 to length-3 in this case (mat[c(TRUE,FALSE),2] would be an
example of incomplete recycling)?
William: clever, but maybe too clever unless you really need the
speed? (The c

It doesn't. I took your subject line to be the theme of your posting and
`incommensurate lengths' to be an instance used to emphasize how silent

I have never used this construct. However, part of my job is seeing how
well CRAN packages work in our reimplementation of the R language
and I am continually surprised by the inventiveness of package writers.

Thank you Mark, this is what I was looking for.
On Sunday I will read again in detail previous discussion's facts, and
attach the pros and cons here, so that they remain for the future, and the
topic can be closed.

I repeat it for all the reason I gave to Duncan on a personal E-mail, It is
a lot of text, and I might be wrong, but I attach it in case it is useful:
A) I feel Version Control (SVN) is great when there is a little group of

In practical terms, failing tests are not preventing anyone from using
an optimized BLAS/LAPACK implementation they trust. Building R with
dynamically linked BLAS on Unix is supported, documented and easy for
anyone who builds R from source. It is also how Debian/Ubuntu R packages
are built by
