Missing values for S4 slots
Using R 2.4, the following fails:
setClass("testc", representation(a="ANY"))
makeC <- function(myarg) new("testc", a=myarg)
makeC()
-> Error in initialize(value, ...) : argument "myarg" is missing,
with no default
On the other hand, this is OK:
f <- function(a) g(b=a)
g <- function(b) if(missing(b)) "missing" else "valid

write.dcf/read.dcf cycle converts missing entry to "NA" (PR#9796)
Full_Name: Bill Dunlap
Version: 2.5.0
OS: Red Hat Enterprise Linux WS release 3 (Taroon Update 6)

If you read a dcf file with read.dcf(file,fields=c("Field",...))
and the file does not contain the desired field "Field",
read.dcf puts a character NA for that entry in its output
matrix. If you then call write.dcf, passing it the output

(PR#9796) write.dcf/read.dcf cycle converts missing entry
BIll,
Thanks.
I am seeing some problems here, for example when all the fields are
missing, or all the fields in a row are missing. I've fixes for those,
and will commit to R-devel shortly.

Linking to lapack
Hello all.
I'm developing a package for R holding a Gibbs sampler, which tends to have
better performance when written in C than in R.
During each iteration in the Gibbs sampler, I need the inverse of a
symmetric matrix.
For this, I wish to use lapack, as is concisely suggested in "Writing R
extensions", since this will have better performance than I could ever write
myself.

strange sprintf() behaviour ?
This is quite strange behaviour - at least for R-novice as myself....
Consider this:
> testf <- function() { x <-2; sprintf("%s %f", "x =", x); return(x) }
> result <- testf()
> testf <- function() { x <-2; sprintf("%s %f", "x =", x) }
> result <- testf()
> testf()

ordering levels: I was wrong
I was wrong about needing the Relevel from the Lexis package.
The default verson of relevel does the job of reshuffling levels
in any desired order, albeit with a warning (which comes from the
fact that apparently only a single number had been anticipated by
the designer):
> testf <- factor( sample( letters[1:4], 100, replace=T ) )
> table( testf, newf=relevel( testf, ref=c(3,2,1,4) )

relevel expansion suggestion
To the R developers,
The discussion below reminded me that I think it might be a good idea
to take the Relevel function from the Lexis package and replace relevel
in stats with it. This is really nothing special for epidemiology.
It is fully compatible with the existing relevel (it actually contains
the
relevel code almost verbatim as a subset), but it has the extra
functionality

Reshape package: new version 0.7
Reshape 0.7
===================
Reshape is an R package for flexibly restructuring and aggregating
data. It is inspired by Excel's pivot tables, and it makes it very
easy to view your data the way you want. The reshape package (along
with ggplot) received the John Chambers Award for Statistical
Computing. You can find out more at http://had.co.nz/reshape.

problem accumulating array within a function over loops
Dear R helpers,
I am having trouble with an array inside a loop.
I wish to accumulate the results of a function in an array within
the function, over several loops of a program outside the function.
The problem is that the array seems to re-set at every entry to the
function. Here is an example, so you can see what I mean.

[LLVMdev] mixed bc file
I have a question with llvm-gcc and llvm-gfortran.
Is it possible that llvm-ld can combine different bc files compiled from C programme and Fortran Programme together?
For example:
Compile a c program into llvm bc file by the task:
# llvm-gcc -emit-llvm test.c -c -o test.bc
and then compile a fortran program into llvm bc file by the task:
# llvm-gfortran -emit-llvm testf.f -c -o testf.bc

ordering levels
Hello!
I would like to know if there is a simple way to reorder levels of a given factor.Let's say that the vector
testf<-factor(c("red","red","red","blue","blue","white"))
levels(testf) : blue red white
should have reordered levels such as
levels(testf) : red blue white
(this is for presentation purposes)

Dreaded RTNETLINK answers: Invalid argument
Hi All,
We are running a 2.4.20 kernel, with the htb modules loaded, and are

access objects
hi,
say I have consecutively numbered objects obj1, obj2, ... in my R workspace.
I want to acces one of them inside a function, with the number given as an argument.
Where can I find help on how to do that? Somebody must have been trying to do this before...
Some keywords to start a search are appreciated as well.
Here's an example, I hope it clarifies what I'm trying to do:
