R-alpha: old Rdoc 2 new Rdoc
--xk+LtGr+JJ
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.

R-alpha: R 0.50.a1: patch for NChisquare documentation
The patch below fixes the NChisquare documentation problem that I've
been mentioning for some time now.
NOTE: There is one DEQN where the LaTeX part contains real LaTeX code,
because I did not see how to get a sum sign (and a roman math font)
otherwise. Seems to work, though ... MARTIN?

Rd problems
Hola!
I have the following in a .Rd file:
\eqn{\mbox{coef} = c(\mbox{coef}[1],\ldots, \mbox{coef}[n]) }
{coef = c(coef[1], coef[2], \dots, coef[n])}
However, both arguments come out in the latex file!
Whats happening?

Using MathJax in R's help system
Hi,
I am doing a small experiment to test if I can use
MathJax ( official site: http://www.mathjax.org )
in R's html help pages (i.e. options(help_type='html'))
and it seems working with some minor modifications.
The screenshot (rendered by Firefox 4.0 beta and with STIX fonts) of
the help page in html format with MathJax enabled is at the following

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

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

Rd problems --- followup
I should'nt have sent the last mail so fast.
Same problem with

{u[j] = a[j] + b*x + c*x^2 j = 1,\dots,r-1}
I thought the problem in the first case could have to do with
the use use of \mbox{} (with the braces) within the arguments
of \eqn, but here there are none braces in the arguments of \eqn{}{}.

Two problems building a package
Hello all:
I have written a few R scripts and am trying to turn them into a package for
submission to CRAN. All of these scripts are R code only, no C or C++ or
anything else. I'm working with R 2.0.1 running on a Windows XP machine. So
far running ">rcmd install --build --docs=normal mypkge" seems to work
(i.e., the library "mypkge" is installed in R\rw2001\library and

Rounding multinomial proportions
I present you with a function that solves a problem that has bugged me for
many years. I think the problem may be general enough to at least consider
adding this function, or a revamped version of it, to the 'stats' package,
with the other multinomial functions reside.
I'm using R to export data to text files, which are input data for an
external model written in C++. Parts of the

Checking your package's help files
It seems that many package authors do not proofread the help installed
with their packages. The Rd converter is not a parser, and it will
silently produce incorrect results on incorrect input (and some correct
input).
Here are a few hints about some common errors:

R-alpha: Equations in Plots
Paul Murrell and I are making some progress with making mathematical
expressions available in graphs. The idea is to use R expressions to
represent the mathematical expressions. So far we have (or will soon
have):

x[i] x_i
alpha \alpha
Alpha \Alpha
hat(x) \hat{x} \widehat{x}
bar(x) \bar{x} \overline{x}

Line breaks in mathematical formulae in Rd files (PR#13287)
Hi,
This is a problem about writing R documentation (R-exts 2.6). The
command "\deqn" defined in "Rd.sty" is:
\newcommand{\deqn}[2]{\[#1\]}
which will put mathematical formulae in the "displaymath" environment;
that means line breaks are not allowed (or will not be shown) in
formulae, but sometimes we do need multiple lines of formulae. One
solution is to write

tabular environment for Rd files
I have added a preliminary version of a tabular environment to Rdconv
and committed it to the current development sources.
Syntax:
\tabular{format}{
aaa \tab bbb \tab ccc \cr
xxx \tab yyy \tab zzz
}
i.e., the column seperator is \tab and the line seperator is \cr
format is a usual LaTeX tabular format string, e.g in the above
example it could be `lll' giving three left justified

Experimental Rd parser in trunk.
I've just committed the parse_Rd() function to R-devel. This is a
parser for Rd files, described in
http://developer.r-project.org/parseRd.pdf
It is not identical to the current parser, and about a dozen of the base
man pages currently signal syntax errors. It also detected errors in 10
files that were errors according to both definitions, but were missed by
the current system, and

nlminb and optim
I am using both nlminb and optim to get MLEs from a likelihood function I have developed. AFAIK, the model I has not been previously used in this way and so I am struggling a bit to unit test my code since I don't have another data set to compare this kind of estimation to.
The likelihood I have is (in tex below)

Maths in R documentation (PR#523)
The document R-exts contains the following example of using
mathematics in R documentation.
\deqn{p(x) = {\lambda^x\ \frac{e^{-\lambda}}{x!}}
{p(x) = lambda^x exp(-lambda)/x!}
There is a syntax error in there, but that's not my point.
The problem is that using "R CMD Rd2dvi" I find that putting
the alternate forms of the equation on top of each other doesn't
work.
