Fixing the HDF5 package: the on.exit mystery
Dear all,
I'm trying to fix a subtle bug in the hdf5 package. This package provides an
interfaces to the HDF5 library and hence allows one to load data into R from
files in the HDF5 format. The bug appeared during a period in which R changed
but the package did not.
I include below both the R and C code, stripped of everything except what is
needed to show the bug. What is supposed to

new book
Just thought I would mention that there is a new O'Reilly book out,
"Developing Bioinformatics Computer Skills", which is ok, pretty
superficial about some things but at least it lets you know what is
happening and where.
R gets a few pages in there, 394-396, mostly nice press and accurate
except that Bill Venables (hi Bill) may be surprised to find out that
he is a member of the

An example (was RE: file connection, while, readLines and bro wser)
Prof. Gentleman (and R-help),
Here's an example of what didn't work. I still don't understand why.
Function:

f.con <- file(file, open="rt")

i <- 0

hdf5 library install issue
Dear all
I'm trying to install the hdf5 library into R. The HDF5 package is
installed in a special directory, distributed accross my cluster:
/share/apps/HDF5
So i put the args option to the configure command as i read in previous
post in the list:
jerome]# R CMD INSTALL --configure-vars='LDFLAGS=-L/share/apps/HDF5/lib'

Building hdf5 for ms-windows
I am trying to build hdf5 for ms-windows. I downloaded the hdf5_1.4.7.tar.gz, gunzipped it and got a tar file. I extracted everything into a directory tree called hdf5. I also found a Makevars.win and libhdf5.def in the R help archives from March 2002. I put those two in hdf5 as well.
I issued the command Rcmd build --binary hdf5

linking hdf5, requires setting LD_LIBRARY_PATH
I am writing an R package to interface to hdf5 files (yes I know one
exists, the issue will be demonstrated using that package). I tend to like
to build/install things locally so that aspects of the system I am working
on don't cause problems later when attempting to install elsewhere. To
this end, I build and install the hdf5 libraries w/out incident:
tar xzf hdf5-1.8.4.tar.bz2

I need to load a hdf5 file, so I installed the hdf5 libraries ad the hdf5 R

could correctly load it. But when I try to load my file:

HDF 5 install - how to pass configure flag to the R CMD command
The basic question is: How can I pass configure script command line flags

Now I try to install the HDF5 package on Linux (SuSE 7.3).
I got hdf5 libraries installed in /usr/local/hdf5 (man/lib/bin).

uploaded hdf5 and R 0.65.1 RPMs
Dear everybody:
HDF5, a dataset formatting library, and R that is built with it, have
been uploaded to ftp://ftp-fis.iarc.fr/pub/incoming. The R RPM uses the
spec file created by Martyn Plummer as a starting point, and makes only
a few trivial changes.

New RH7.2 rpms for R-hdf5 support available
HDF5 is a high quality data storage format from NCSA
(http://hdf.ncsa.uiuc.edu/index.html) Marcus Daniels of the Swarm
Development Group has made available an R library called hdf5 which
allows loading and saving of data in hdf5 format. The source for his
library is here:

Memory problems, HDF5 library and R-1.2.2 garbage collection
Hello:
I've recently started using R to process data in HDF5 format. My files
come in 1.5MB chunks, but they can be as big as 50MB.
The problem I am facing with R-1.2.2 is that when I try to load 50 of
the 1.5MB HDF5 files (using the hdf5 library) in a loop, my Linux box
gets close to its memory limit around the file #15 (256MB RAM and
256MB swap). This happens even if I load file ->

R and HDF5 Question
Hello All,
I just signed up to this list, so I apologize if this question has been
asked before.
I am trying to load an hdf5 file into R and running into some problems. Here
are the steps I took to configure my environment:

* hdf5 1.8.3 installed via macports
* hdf5_1.6.9.tar.gz from CRAN

R RPMS and HDF5
Greetings
I'm new to R. I became interested in it because my friends at the Swarm
Development Team at the Santa Fe Institute have been using/developing R
to work as a front end for HDF5 datasets.
>From looking at the RPMS for R, I got the idea they were compiled
without support for HDF5. Correct?

Building hdf5 on Windows
Hi all,
I try to use the hdf5 package. I downloaded the Windows binary version, and
it claims it requires hdf5dll.dll library, so I download the whole hdf5
1.4.3 package from NCSA. Unfortunatelly, it crashes R. I suspect it is
because the package was probably compiled against version 1.2 of hdf5 (as
evoked in the help file?) or any other previous version, so I downloaded the

hdf5 package segfault when processing large data
Hi there,
I am currently working on something that uses hdf5 library. I think
hdf5 is a great data format, I've used it somewhat extensively in
python via PyTables. I was looking for something similar to that in R.
The closest I can get is this library: hdf5. While it does not work
the same way as PyTables did, but it's good enough to let them
exchange data via hdf5 file.

Problem with package hdf5-1.4.7 in R-1.7.1
Hello:
Has anyone successfully installed the package hdf5-1.4.7 in R version
1.7.1? I get a fatal error with a core dump (see below) whenever I try
to use hdf5load.
Since I'm in the process of moving to a new machine, I'm not sure
whether this is due to (my installations of) the HDF5 libs or the hdf5
package for R. Just for the record, the HDF5 data files were correctly
generated in the
