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 ./

compress data on read, decompress on write
Dear All,
I'd like to be able to have R store (in a list component) a compressed
data set, and then write it out uncompressed. gzcon and gzfile work in
exactly the opposite direction. What would be a good way to handle
this?
Details:
----------
We have a package that uses C; part of the C output is a large sparse
matrix. This is never manipulated directly by R, but always by the C
code.

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

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)
--with-system-bzlib \
--with-system-pcre \
--with-system-zlib \
I wonder if these are still necessary and, in fact, when building R alpha
(specifically, R-alpha_2016-03-21_r70361.tar.gz) I get a warning saying

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.

colors for background and plotting area
Dear all,
I am trying to prepare some figures where I'd like the color of the plot region
(i.e., the area bounded by the axes) to be different from the margin area
(i.e., the area of the figure not within the axes region). I can use "bg" but
that changes the background of everything? How can I accomplish what I want?
Thanks,
Ramon

R_alloc with structures with "flexible array members"
Dear All,
In a package, I want to use some C code where I am using a structure
(as the basic element of a linked list) with flexible array members.
Basically, this is a structure where the last component is an
incomplete array type (e.g., Harbison & Steel, "C, a reference
manual, 5th ed.", p. 159) such as:
struct Sequence {
struct Sequence *next;
int len;

make check fails with default libblas
Dear All,
Summary:
========
To test some packages, I want to build R-3.1.0 (current R devel). However,
when I use the default libblas, make check fails with
running code in 'reg-BLAS.R' ...make[3]: *** [reg-BLAS.Rout] Error 1
It does not fail, however, if I use libatlas3 or libopenblas.
The same thing happens with the current R patched.

returning vectors of unknown size from C (with .C)
Dear All,
In a package, I am using ".C" to call some C functions. In one case,
the number of elements of the return vectors are not known in R before
the C call. (Two of the vectors are integers, the third is vector of
character strings).
Passing from R a vector of the maximum possible size would be a huge
waste. I understand one alternative is to use ".Call", but I'd

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

validate (rms package) using step instead of fastbw

For logistic regression models: is it possible to use validate (rms

More details:
I've been using the validate function (in the rms package, by Frank

URW Fonts Description in Installation and Administration Manual
Good day,
In section A.2, the manual advises "Linux users will want the urw-fonts package". However, this package only seems to be available for RedHat Linux and Fedora Linux. What about for Debian or Ubuntu ? There is no urw-fonts package for them. Are there any other packages not mentioned that are important for these two distributions ?

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
(?).

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,
