Am I missing something or is my copy of R 1.9.0pat corrupted?
(This is under Windows 2000.)
Thanks Much!

Making iconv portable?
...bNonStandardCharacters? function in the Ecfun package. The development version on R-Forge uses this and returns ?Raul? under Windows and NA under Mac OS X (and presumably also Linux).
The ?iconv? R code merely calls compiled code, which I?ve used very little in 30 years.
Thanks,
Spencer

vector documentation error?

Should I bother to report such things? If yes, to whom?
Thanks for all your hard work to make R a reality. It makes it so
much easier to develop new statistical methods for almost any purpose
and through that to contribute to building a better world for all.
Sincerely, Spencer Graves
p.s. Please excuse if I'm sending this to the wrong address. I went to
www.r-project.org -> Mailing Lists and double clicked on an apparent hot
link to "r-bugs" and got nothing (in Netscape 7.1 under Windows 2000).
Therefore, I decided to send this to r-devel.

rpois(9, 1e10)
...: int 4; otherwise
the same as on my Mac.
????? Am I correct that $ sizeof.long = 4 means 4 bytes = 32 bits?
log2(.Machine$integer.max) = 31.? Then 8 bytes is what used to be called
double precision (2 words of 4 bytes each)?? And $ sizeof.longdouble =
16 = 4 words of 4 bytes each?

Gaussian Quadrature for arbitrary PDF
Hi all,
We know that Hermite polynomial is for
Gaussian, Laguerre polynomial for Exponential
distribution, Legendre polynomial for uniform
distribution, Jacobi polynomial for Beta distribution. Does anyone know
which kind of polynomial deals with the log-normal, Student抯 t, Inverse
gamma and Fisher抯 F distribution?
Thank you in advance!

General expression of a unitary matrix
Hi, all,
Does anybody got the most general expression of a unitary matrix?
I found one in the book, four entries of the matrix are:
(cos\theta) exp(j\alpha); -(sin\theta)exp(j(\alpha-\Omega));
(sin\theta)exp(j(\beta+\Omega)); (cos\theta) exp(j\beta);
where "j" is for complex.
However, since for any two unitary matrices, their product should also
be a unitary matrix. When I

optim(…, method=‘L-BFGS-B’) stops with an error message while violating the lower bound

larger vignette fitting several models that seem to encounter
convergence problems. I should probably switch to optimx using all the

...for a larger integer range for R integer

But it isn't easy to get right, so it may take some time. I doubt
anything can happen for R 4.0.0 this year, but 2021 may be possible.

I installed lme4, maps, mapproj, CircStats, scatterplot3d, gregmisc,
Hmisc without problems. To confirm, 'library(lme4)' produced the
following error:
Error: package 'Matrix' required by 'lme4' could not be found
What do you suggest?

p.s. I get the same result using several different (US) mirrors.

can either add passphrase to the default keys, or create another set of
