Hi Fellows from R-Help List!
My questions are basic since i an new with R. I am very acquainted with Matlab &
Gauss (the compentence, I guess). Anyhow,

feed a particular option with many variations coming from a text file. Is this
possible with the free version? For instance, there exists the eval comand in

Automating citations in Sweave
Dear all,
Is there an elegant way to add citations of packages when using Sweave?
Ideally I'd like a function which creates a Bibtex-file with the
packagenames as keys. The idea is to use \cite{packagename} or \cite{R}
in LaTeX.
I know you can get the Bibtex entry with
toBibtex(citation("packagename")). But after updating R or a package one
needs to update the bib-file too. When

matlab-like constant matrix initialization?
Hi all,
Suppose I have the following matrix which is a constant matrix I've copied
from some other document:
1.2 3.4 1.4 ...
2.3 3.7 2.6 ...
...
How do I make it into a matrix or array in R?
What is the fastest way of initializing a constant matrix with this
copy/pasted values?
Thanks a lot!

Collapsing Categorical Variables
Hi,
Suppose I have a categorical variable called STREET, and I have 30
levels for it (i.e. 30 different streets). I want to find all those
streets with only 15 observations or below then collapse them into a
level called OTHER. Is there a quick way, other than using a for()
loop, to do it? Currently what I'm doing is something like:
### Collapse STREET (those < 15)
st <- c()

a loop question
I want to get three .gif image files test.1.gif,
test.2.gif, & test.3.gif by using a loop. The code I
tried is like this:
x=c(0, 1, 2, 3, 4)
y=c(1, 2, 3, 4)
for(i in 1:3)
{
x11()
jpeg("test.i.gif")
plot(x, y)
dev.off()
}
but I only could get one image file, test.i.gif. How
can I get three image files?
Thanks.

Decision Trees
I am familiar with the rpart and tree packages for classification and
regression trees. However, quite a bit of the research in the
transportation community relating to decision trees uses the C4.5 family of
algorithms by Quinlan. Are there any plans to make a C4.5 (or a derivative
of it) available to R? If not, then I might use the WEKA Java package (

confidence intervals for y predicted in non linear regression
Hi, I´m trying to plot a nonlinear regresion with the confidence bands for
the curve obtained, similar to what nlintool or nlpredci functions in Matlab
does, but I no figure how to. In nls the option is there but not implemented
yet.
Is there a plan to implement the in a relative near future?
Thanks in advance, Florencio

plot
Hi,
How could I plot two vectors on the same graph? For example, if I have two
lists of results, each list is a vector. I want to display them on the same
graph, so I can compare them. How could I do that?

Book on R programming
Most books on R I come across describe running statistical procedures in R.
Any suggestions on a good book that teaches *programming* in R?
Thanks,

An lgrind definition for the S language
I seem to recall discussion of an language definition file for S for
use with the lgrind utility but I can't find any trace of it in an R
Site Search. The lgrind utility takes a file of code in a particular
programming language and prepares it for "pretty printing" in LaTeX.
In my version the available language definitions are

How do I add a book title to the R bibliography?
R community:
I would like to add a new title to the bibliography on the R website
(http://www.r-project.org/doc/bib/R-books.html), but I cannot find
instructions for doing that.
Can anyone tell me, whom should I contact in order to add a new book?
(I added the title to the wiki's list of books, but the bibliography and the
list don't seem to be connected.)
Thank you!

Need car() and cdr() for '...'
Needed to redefine function "sum" for my MATLAB package.
There's something similar in Chambers's Green Book (pg 351)
so I modified it as such:
library(methods)
setGeneric("sum", function(x, ..., na.rm = FALSE) {
if (nDotArgs(...) > 0)
sum(c(sum(x, na.rm = na.rm),
sum(..., na.rm = na.rm)))
else
standardGeneric("sum")
})

Samba 3.0.28 with VFS-Module "GPFS"
Hi Rob,
on your Info for Version 3.0.25 you pointed out the VFS-Module GPFS for
using features of the underlaying GPFS-Filesystem.
Also the man-pages-3/vfs_gpfs.8.html points to that module, but I can't
find it anywhere.
We are using a GPFS 3.2 3-Node Samba Cluster (3.0.24/28) on Dell HW.

How to google for R stuff?
Hi! I'm new to R programming, though I've been programming in other
languages for years.
One thing I find most frustrating about R is how difficult it is to use
Google (or any other search tool) to look for answers to my R-related
questions. With languages with even slightly more distinctive names like
Perl, Java, Python, Matlab, OCaml, etc., usually including the name of the

john chambers R book
Just to let everyone know: John Chambers R book is no longer at
pre-order status on Amazon which is a good thing. The only problem
is that now it is temporarily out of stock. There must have been many
pre-orders so now I'm kicking myself for not having done that.

bibtex::read.bib -- extracting bibentry keys
I have two versions of a bibtex database which have gotten badly out of
sync. I need to find find all the entries in
bib2 which are not contained in bib1, according to their bibtex keys.
But I can't figure out how to extract a list of the bibentry keys in
these databases.
A minor question: Is there someway to prevent read.bib from ignoring
entries that do not contain all required fields?

Book on R's Programming Language
Can someone please recommend to me a book on the programming language that R is based on? I'm looking for a foundational book that teaches the logic of the S language. It seems that knowing the underpinnings of the language can only make using R a bit easier.
Any leads are greatly appreciated . . .

Text file encoding
I'm working with some people using apple laptops. When we share text
files (latex files), I reach in an encoding problem on our CentOS
laptops and desktops. In my favorite editor, "?" is "<8e>", "?" is
"<88>" etc...
Of course, I can change the encoding with iconv:
iconv -f MACINTOSH -t ISO8859-15 file.bib.mac >file.bib
iconv -f
