I'm continuing my work on finding speedups in generalized inverse
calculations in some simulations. It leads me back to .C and .Call,
and some questions I've never been able to answer for myself. It may
be I can push some calculations to LAPACK in or C BLAS, that's why I
realized again I don't un
Speaking of optimization and speeding up R calculations...
I mentioned last week I want to speed up calculation of generalized
inverses. On Debian Wheezy with R-2.15.2, I see a huge speedup using a
souped up generalized inverse algorithm published by
V. N. Katsikis, D. Pappas, Fast computing of t
-2.15.2? I should have thought of that before, I suppose
:)

2 days ago, I posted my long message about the observed slowdown in a
package between R-2.15.0 and R-2.15.2.
Uwe Ligges urged me to make a self-contained R example. That was the
encouragement I needed. I tracked the problem down to a failing use of
a LAPACK routine.
R's LAPACK C interface changed

ckage writers don't follow my suggestion, what do they think they
should do instead?

I hope you are doing well.
For me, this was an unexpected problem. I've hoped for quite a few
wrong things today, but I'm only asking you about this one. Why does
ifelse(1, list(a, b, c), list(x, y, z))
return a list with only a, not list(a, b, c) as I hoped. I wish it
would either

Hello, everybody.
I recognize I'm asking you to deal with a not-very-important problem.
But its important to me :)
I've noticed a little inconsistency in the print.function() output. I
traced the matter to deparse.c, for which I attach a patch that
addresses 3 separate things. There's one importa
OK, I concede that.
Now, how about "} else {"
I will provide patch that does only that change.
