R-alpha: old Rdoc 2 new Rdoc

Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit
Attached is a conversion script for converting current R doc files to
the proposed new format ... I'm not sure if it handles everything
correctly, as I made just some random checks. The main purpose for
posting the thing to the list is such that those interested can get a
look at the new format.

problem building dvi and pdf documentation on Darwin 10.2.6
I just installed R-1.7.0 on Darwin 6.6 (a.k.a. MacOS 10.2.6).
'make' and 'make check' run without any problems. 'make info'
builds with no complaints, but 'make dvi' and 'make pdf' fail.
I get refman.dvi and refman.pdf OK (with some warnings from
pdftex that some names are referenced that do not exist), but
R-FAQ.{dvi,pdf} fails as shown below. Attempts

optim or nlminb for minimization, which to believe?
I have constructed the function mml2 (below) based on the likelihood function described in the minimal latex I have pasted below for anyone who wants to look at it. This function finds parameter estimates for a basic Rasch (IRT) model. Using the function without the gradient, using either nlminb or optim returns the correct parameter estimates and, in the case of optim, the correct standard

Weighted median
Is there a weighted median function out there similar to weighted.mean()
but for medians? If not, I'll try implement or port it myself.
The need for a weighted median came from the following optimization
problem:
x* = arg_x min (a|x| + sum_{k=1}^n |x - b_k|)
where
a : is a *positive* real scalar
x : is a real scalar
n : is an integer
b_k: are negative and positive scalars

Error when using buildVignettes()
Dear all,
When running function 'testQAReport()', which uses function
'buildVignettes()' to create a pdf-file I get the following error:

Error in .get_package_metadata(pkgdir) :

GLS with corAR(1) correlation structure residual/standard error calculation
I am using the gls function to fit a two-stage least squares model with
first order autoregressive error terms. Since there is no automated
adjustment for the use of two-stage least squares in this package, I am
trying to manually replicate standard errors of the coefficient estimates in
order to adjust for a first stage OLS estimate of endogenous variables.
However, thus far I have been unable to

Generación de números aleatorios. Mixtura k-puntos
Saludo cordial para cada uno.
Les pido ayuda para generar números aleatorios de una mixtura k-puntos.
Sabemos que la función de distribución F es una mixtura k-puntos si es de
la forma F(x) = p_1 F_1(x) + p_2 F_2(x) + … + p_k F_k(x), donde F_j es una
función de distribución de probabilidad, p_j > 0 y suma(p_j) = 1, para j =
1, 2, …, k.
En mi caso particular F es la suavización de la

mdct explanation
...as promised.
This describes the mdct used in my d.m.l patch. I think it is the
same as the Lee fast-dct.
I typed it in a kind of pseudo-TeX, 'cause the ascii art would
kill me. Hope you can read TeX source; if not, ask someone who
can to make a .ps/.gif/.whatever of the TeX output, and put it
on a webpage or something. I'm to lazy to do it (and besides, I

(OT) Fourier coefficients.
This posting has nothing to do with R (except maybe that I am using R
very heavily in writing the paper to which the question pertains.) I
simply wish to draw upon the impressive knowledge and wisdom of the R
community.
Since this question is way off topic, if anybody has the urge to
reply, they should probably email me directly:

Suggestion for quantile.default()
I'm not sure who is responsible for quantile(), but I assume they read
this list. Ivan Frohne and I have produced a revision of the
quantile.default() function which enables the computation of alternative
sample quantile definitions. The code and .Rd file are attached.
This enables the user to produce quantiles that are equivalent to those
in various statistics package. There is a type

More mdct questions
Sorry for starting another topic, this is actually a reply to Segher's post
on Sun Oct 22 on the 'mdct question' topic. I wasn't subscribed properly
and so I didn't get email confirmation and thus can't add to that thread.
So Segher, if the equation is indeed what you say it is, then replacing
mdct_backward with this version should work, but it doesn't.
