using zlib (was compress data on read, decompress on write)
Dear All,
I think I am confused about how I'd be able to use zlib starting with
R 2.7.0. I just downloaded the latest development version, built it,
etc, but I am not able to find the zlib.h that, I believe, R should
place somewhere under "where/you/want/R/to/go" (from
--prefix=/where/you/want/R/to/go). There seem to be entry points for
zlib in the binary (e.g., grep -r gzopen ./

Rserve and R to R communication
Dear All,
The "clients.txt" file of the latest Rserve package, by Simon Urbanek,
says, regarding its R client,
"(...) a simple R client, i.e. it allows you to connect to Rserve from
R itself. It is very simple and limited, because Rserve was not
primarily meant for R-to-R communication (there are better ways to do
that), but it is useful for quick interactive connection to an

using zlib in a package: problems in windows
Dear All,
I am having trouble getting an R package to build and install
correctly under Windows. In this package, which builds and checks OK
under Linux, I use zlib (among other functions, gzprintf).
As mentioned by Prof. Ripley a while back, the file "CHANGES" under
src/gnuwin32 says explains that to, to use zlib, one has to set
$(ZLIB_LIBS) in PKG_LIBS. I have a Makefile.win with

eval(parse(text vs. get when accessing a function
Dear All,
I've read Thomas Lumley's fortune "If the answer is parse() you should usually
rethink the question.". But I am not sure it that also applies (and why) to
other situations (Lumley's comment
http://tolstoy.newcastle.edu.au/R/help/05/02/12204.html
was in reply to accessing a list).
Suppose I have similarly called functions, except for a postfix. E.g.

Any mountain clustering method in R?
Dear all,
I wonder which R algorithm could perform a mountain clustering in an spatial
grid, in other words, having the coordinates of a map (x,y ... or even more)
and then the altitude/height at each point I would like to localise the
peaks of that topological surface. Which R algorithm can perform this? I see
it as a clustering problem where the peak should be at the center of each
cluster.

DNAcopy package in R
Hi All:
Has anyone analyzed Illumina 550K data using DNAcopy package? I have around
2300 samples. According to
Venkatraman and Olshen 2007 paper, it needs about 25 min to run a single
sample for Affymetrix 100K. I am afraid it will take too long to analyzed my
data. Anybody has an idea? Thanks!
Best,

trouble with snow and Rmpi
Dear R People:
I am having some trouble with the snow package.
It requires MPICH2 and Rmpi.
Rmpi is fine. However, I downloaded the MPICH2 package, and installed.
There is no mpicc, mpirun, etc.
Does anyone have any suggestions, please?
Thanks in advance!

snow makeCluster (makeSOCKcluster) not working in R-2.11
Hello,
I was using snow to parallel-process some code in R-2.10 (32-bit

dendrogram: how to obtain leaf height
Dear All,
How can the height of a leaf be extracted from a dendrogram?
Sure, I can print it, but I am not able to, say, store it in an object. I think I understand that the height is a property of the split, not the leaf itself, but the printing functions display a "height" or "h" (which changes with "hang") and that is what I want. Obviously, the info is there

But sadly it disappeares after a second or two. How can i make it to wait
until i press a key or something?
thank you.

Looking for packages to do Feature Selection and Classification
Hi All,
Sorry if this is a repost (a quick browse didn't give me the answer).
I wonder if there are packages that can do the feature selection and
classification at the same time. For instance, I am using SVM to classify my
samples, but it's easy to get overfitted if using all of the features. Thus,
it is necessary to select "good" features to build an optimum hyperplane
(?).

Package for phylogenetic tree analyses
Hi
I am looking for a package that
1. reads in a phylogenetic tree in NEXUS format
2. given two members/nodes on the tree, can return the
distance between the two using the tree.
I came across the following packages on CRAN
ouch, ape, apTreeShape, phylgr all of which seem to
provide extensive range of functions for reading in a
Nexus-format tree and performing phylogenetic

Snow vs Rmpi
Hi,
I have few high-level questions about the Snow and Rmpi packages . I understand that Snow uses Rmpi as one of possible transport layers, yet my questions about user experience, not technical details:
1. Does Snow install and work well in Windows?
2. Interruptibility. I understand that currently it is impossible to interrupt a running top-level command in Snow ( Ctl-c or the likes), the

bzlib, pcre and zlib still needed in rules?
Dear All,
I just
apt-get source r-base-core
and noticed that file "rules" under ./r-base-3.2.4-revised/debian
contains (lines 277 to 279)

I wonder if these are still necessary and, in fact, when building R alpha

simultaneous computing
Hello,
which possibilities are available in R for simultaneous or parallel
computing?
I only could find biopara
(http://cran.r-project.org/src/contrib/Descriptions/biopara.html)
Are there other possibilities?
Are there special groups working on simultaneous computing with R?
Thanks

Valores faltantes en SVM aplicado a microarrays
Hola,
Quería preguntar si alguien conoce alguna referencia que pueda ayudarme a
entender cuál es la mejor forma de lidiar con valores faltantes para aplicar
svm en datos de microarrays. Estoy pensando que una buena solución es
eliminar la variable en la que exista un valor faltante de la matriz de
datos. En el paquete e1070 de R se elimina la muestra que contiene valores
faltantes, pero eso para
