S3/S4 classes performance comparison
Hi R-devel,
If you did read my survey on Rhelp about reporting, you may have seen that
I am implementing a way to handle outputs for R (mainly target output
destinations: xHTML and TeX).
In fact: I does have something that works for basic objects, entirely done
with S4 classes, with the results visible at:

cor, cov, method "pairwise.complete.obs"
Hi UseRs,
I don't want to die beeing idiot...
I dont understand the different results between:
cor() and cov2cov(cov()).
See this little example:

Copyright issues question
Hi to the Devel list,
I am at present developping a little Excel add-in that would consist into a
translation of John Fox RCommander package.
The idea is to have R code that recreates within Excel the menus and some
VBA part that handles data input and outputs (those beeing redirected to
HTML and imported within Excel in a user-transparent way).

R2HTML version 1.4-3
Hi useRs,
I have uploaded on CRAN R2HTML version 1.4-3, which should be available
soon for your favorite platform.
For R 2.0.0, I had to rewrite some parts of the code so that it works. I
did that quickly (maybe too), letting some bugs.
Now, this is mere the good R 2.0 version, with some new functionalities:
- HTML.matrix and HTML.data.frame now can use several new output options

merge.list proposal
Hi R-devel,
Today I was needing a way to "merge" two different lists (see the example
for my definition of merge). I didn't find anything relevant using
different search methods.
So, here is my proposal to add a list method for "merge".
Best wishes,
Eric
PS: AFAIK, there still is no place for code snipplets. I am not sure this

c(recursive=TRUE)
Hi R users,
I am currently using c(...,recursive=TRUE) to handle list-structured
objects.
This allows to represent something like:
> l1 = list(level1=1,level2=list(sub1=1,sub2=2))
as:
> (l1names = names(c(l1,recursive=TRUE)))
[1] "level1" "level2.sub1" "level2.sub2"
Then, one can use:
> (l1names = sapply(l1names,FUN=function(element)

ROMA project (R Output MAnager) / Progress report / Call for contributors
Hello useRs,
This email is about the ROMA project, the implementation in pure S of a
reporting system for R. Several month ago, I did then send on R-help a
survey on that (mainly: what features did you expect for a reporting
system). During the following months, I did try different approaches for
the core functionalities, ending now with a set of generic functions of
which I am satisfied. More

Differences between "$" and "[["
Hi,
If I define the following list:
> (l<-list("text-align"="right"))
$"text-align"
[1] "right"
I know that I can't use l$text-align, as the parser will find a '-' operation.
If I want (need) to use special names, as "text-align", I have to enclose
it between "". So I can use:
l$"text-align" or

[Wish]: Add "..." argument to library function
Hello,
I would find it very usefull to have the ability to load packages with options.
Consider for example the SciViews package Philippe and me are working on.
When loading on Windows, it automatically loads the associated GUI
executable. It should be convenient to have an option not to load the exe
but still have an access to the R functions of the package.
For that, I think a simple change

Suggestions for packages / help / index (long mail)
Hi R-users and developers,
This month may have seen one of the biggest thread never seen on R-related
mailing lists, the one about "GPL software" and "hidden costs" (at this
day, thread is still open - and active!).
Lot's of mails in this thread are not really relevant to the original mail,
send by Philippe Grosjean.
Nevertheless, most of the mails are of interest and

S4 methods and polymorophism
Hello R Power Users,
There is a rather large introduction you may skip to go directly to
my question about S4 classes.
I am working on some toy code to help me get in through S4 classes.
Doing this homework, I have some questions about S4 classes. I have
carefully read available help and some additional material such as Robert

I am trying to better undertand what we would call "functional paradigm"
use of S/R to better map my programming activities in other languages.

have it's own class):

Argument visible of addTaskCallback
Hello,
I have a question about addTaskCallback
It is said that the argument visible allows to know wether the result of
the top-level evaluation was printed or not.
Nevertheless, in the following example, I encountered a problem, as it
seems not all printed objects are visible...
Could someone tell me where is the tip?

[survey] R for Reporting - the R Output MAnager (ROMA) project
Hi R UseRs,
I am interested in providing Reporting abilities to R and have initiated a
project called R Output MAnager (ROMA).
My starting point was my R2HTML package which provides (rough) HTML
exportations. I began with trying to mimic it for LaTeX but fastly did
realize that it was a bad idea.
Thus, I started again from scratch a new package and did spend a lot of
time reading about this
