R2HTML doesn't split paragraphs originating from \Sexpr[results=rd]

What does \Sexpr[results=rd]{} exactly mean in Rd?
Hi,
I have spent a few hours on the R-exts manual and the documentation of
parse_Rd() (as well as the PDF document in the references), but I
still have not figured out what results=rd means. I thought I could
use an R code fragment to create an Rd fragment dynamically. Here is
an example, in which I was expected the output to be a describe list
<DL> in HTML, but it turns out not to be true.

Changes to Rd handling in R-devel
I've just committed some fairly big changes to R-devel.
- There's a new tag \Sexpr which allows R code to be embedded within
the Rd file, similar to Sweave, \RdOpts
corresponds to \SweaveOpts.
- The parser now mainly issues warnings, rather than errors, in case
of syntax errors. It throws away a few tokens and tries to restart.
This should let you see most of your errors in

file.system() in packages
Hello. R-devel, r61697.
I am having difficulty interpreting section 1.4 "Writing package
vignettes" of the R-exts manual. Specifically, I want to use
system.file() in some of my packages to locate a bib file,
uncertainty.bib, which is part of the emulator package. I only want
to maintain a single .bib file.

Dynamic help pages
I've just committed code that allows R to be built with support for
dynamic help pages using \Sexpr in Rd files. Define USE_NEW_HELP and
the R function tools:::.convertRdfiles will be used instead of the Perl
RdConv script, supporting \Sexpr and using the new R converters.
Currently only text help has the macros evaluated when the user asks for
help; the others are rendered at install

columnames changes behaviour of formula
Hello. precompiled R-2.15.0, svn58871, macosx 10.7.4.
I have discovered that defining column names of a dataframe can alter the
behaviour of lm():
d <- c(4,7,6,4)
x <- data.frame(cbind(0:3,5:2))
coef(lm(d~ -1 + (.)^2,data=x))
X1 X2 X1:X2

OK, so far so good. But change the column names of 'x' and the behaviour
changes:

R CMD check problem
Hi
I have a package that I'm testing.
It seems to install fine and it works, as far as I can tell.
For example, I can install the package, and use it,
and source the test suite with no errors.
My problem is with R CMD check.
It passes on R-2.2-0:

array extraction
hello everyone.
Look at the following R idiom:
a <- array(1:30,c(3,5,2))
M <- (matrix(1:15,c(3,5)) %% 4) < 2
a[M,] <- 0
Now, I think that "a[M,]" has an unambiguous meaning (to a human).
However, the last line doesn't work as desired, but I expected it
to...and it recently took me an indecent amount of time to debug an
analogous case. Just to be explicit, I would

R CMD check for packages in a bundle
Hi
[MacOsX 10.4.6; R-2.2.1]
I have a bundle that comprises three packages. I want to run R CMD
check on
each one individually, as it takes a long time to run on all three.
I am
having problems.
The bundle as a whole passes R CMD check, but fails when I cd to the
bundle
directory and run R CMD check on a package directory.
The whole bundle passes:

Visualizing complex analytic functions using domain coloring
Hi
has anyone coded up domain colouring for visualizing complex analytic
functions
(such as elliptic functions)?
[
the idea is to depict a complex function f(z) using a filled.contour()
variant
in which the hue is given by Arg(f(z)), and the saturation by Mod(f(z)).

package installation problem

NAMESPACE problems
Hi.
I am having difficulty following section 1.6.6 of the R-extensions manual.
I am trying to update the Brobdingnag package to include a NAMESPACE file (the
untb package requires the Brobdingnag package).
Without the NAMESPACE file, the package passes R CMD check cleanly.
However, if I include a NAMESPACE file, even an empty one, R CMD check
gives the following error in 00install.out:

Inf +1i vs 1+Inf*1i
Hi
If I have
a <- Inf + 1i
then
Re(a) is Inf, and Im(a) is 1, as expected.
But if
b <- 1 + Inf * 1i,
then
Im(b) = Inf , as expected, but Re(b) = NaN, which I didn't expect.
Why this asymmetry? How to define an object with Re(b)=1, Im(b)=Inf?

S3 best practice
Hello everyone
Suppose I have an S3 class "dog" and a function plot.dog() which
looks like this:
plot.dog <- function(x,show.uncertainty, ...){
<do a simple plot>
if (show.uncertainty){
<perform complicated combinatorial stuff that takes 20 minutes
and superimpose the results on the simple plot>
}
}
I think that it would be better to somehow

Sweave and complex numbers
Hi
When using Sweave, most of my functions get called with complex
arguments.
They get typeset in with additions that I don't want; "1+1i" appears
as "1 + (0 + 1i)"
and I would rather have plain old "1+1i".
Example follows:

largest acceptable lookup table in a package

One of my packages needs a look-up table of pre-calculated
numbers in the data directory.
I would like to have the matrix as large as possible.
What is the largest size matrix that would be an acceptable datafile in
an R package?

The table is a square, upper triangular matrix
consisting of logs of Stirling numbers calculated by Maple.

lines() and recycled colours

For 'type = "h"', 'col' can be a vector and will be recycled as

Why doesn't lines() recycle colours for other types?
If I type

then all ten lines are red, with no warning given. Is there a reason

size of subplots with par() / layout()
Hi
If I do this:
par(mfrow=c(2,2))
persp(matrix(1:4,6,6),box=F,phi=33,theta=33)
persp(matrix(1:4,6,6),box=F,phi=33,theta=33)
persp(matrix(1:4,6,6),box=F,phi=33,theta=33)
persp(matrix(1:4,6,6),box=F,phi=33,theta=33)
(
or indeed
layout(matrix(1:4,2,2))
persp . . . .
)
then the mesh plots look too small to me. How do I make them larger?
