"xpdrows.data.frame" (PR#131)
This is a follow-up to bug sent to days ago, which bounced from r-devel
because
the example was to large. Now example is smaller, and behaviour is as
belo,
EXEPT that r-windows not any more bombs, so main problem is
"xpdrows.data.frame"???
By the way, how to debug this example under windows? debug() doesnt

the functions used (.Primitive), and R wont run under gdb --- may have

reading a character translation table into R
I have a txt file (attached) that defines equivalents among characters
in latin1 (or iso-8859-1), numeric &#xxx; codes, HTML entities
and latex equivalents. A portion of the file is shown inline below, but
may not be rendered well in this email.
I'd like to read this into R to use as a character translation table,
but am stuck on two things:

table( , exclude=NULL) for factor objects
The NEWS file for R-1.7.0 says:
table() now allows exclude= with factor arguments (requested by
Michael Friendly).
But in a recent R-1.7.1beta:
> test <- c(1,2,3,4,5,1,2,3,4,5,NA,NA,1,2,3,4,5)
> table(test)
test
1 2 3 4 5
3 3 3 3 3
> table(test, exclude=NULL)
test

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?

Off-Topic: LaTeX package listings
Hola!
I ask here since I learnt from this list that the LaTeX package listings
should be good
for typesetting R code. I encountered one problem:
\begin{lstlisting}
X %*% V
\end{lstlisting}
in the output the * in %*% disappears! same with %/%, etc, the /
disappears.
Any ideas?

Incompatibility with VGAM
I just discovered that when the VGAM package (not on CRAN) is loaded,
glm() doesn't work. This is because VGAM defines a family function()
which gets found
by glm() in place of the family function from stats.
Then VGAM:::family returns an object which doesn't have a $family
component, (it has a component
$vfamily).
I thought namespaces should protect us from this happening?

as.list.matrix
I found the need of converting a matrix into a list of its columns
(for use with do.call), and was surprised there was no method
as.list.matrix, it could easily be a part of as.list default
I wrote
my.as.list.matrix <- function(mat) {
if(!is.matrix(mat))stop("Argument must be a matrix")
n <- NCOL(mat)

foreign(read.spss) in rw2000 and re2001beta
I encountered something strange with read.spss (package foreign, version
0.7 with R2.0.0 and
version 0.8 with R2.0.1 beta, windows XP)
I made a test file test.sav with SPSS version 11.5.1
containing only one numeric variable, with a value label
for one value not occuring in the file. According to ?read.spss
this should result in a factor, but it results in all NA. Using the

converting factor to numeric
Hola!
The R FAQ says:
7.12 How do I convert factors to numeric?
It may happen that when reading numeric data into R (usually, when
reading in a file), they come in as factors. If f is such a factor
object, you can use
as.numeric(as.character(f))
to get the numbers back. More efficient, but harder to remember, is
as.numeric(levels(f))[as.integer(f)]
In any case, do not call as.numeric()

strange error with rw2010dev
With rw2010dev I get a strange protect(): protection stack overflow
error with a small data frame which otherwise is usable:
If anybody wants to have a look I can provide an RData file
with the problematic data frame.
Doesn't seem to be necessary, the following simulated example
generates the error:
