Dear R Users,
How do we read netcdf / hdf format files in R ?
Also, can we convert netcdf to hdf format in R?

hdf library for windows
The question puzzled me at first, because of your use of "library". It
looks as if the hdf5 r "package" utilises the "windows hdf5 library"
binary.
My reading is that you will have to compile the package yourself after
you have downloaded the hdf windows dll from hdf.ncsa.uiuc.edu The
instructions are in win.readme.txt of the package source which you can
download at

R and hdf
Hi,
I've been playing with R for only a few days, so I'm not terribly
familiar with it yet. Has anyone ever done any work using HDF or
NetCDF files with R? Both file formats have libraries which can be
linked to a program to read and write data to these formats. Is this
sort of thing possible with R? We are planning to use the HDF format to
store experimental data collected by some

samba server file read size limit of 64MB for HDF files
Sorry if that's a vague subject, but this problem is a little weird and I'm just wondering if there are any suggestions out there.
We've got a Samba server (3.0.23) running on a CentOS 5.3 server offering up a data share of 7TB on an XFS filesystem. The authentication all happens through a Samba PDC with an LDAP backend all on a different server. The system in question is just a

how to read hdf files under R?
Hi!
I am trying to install in my R environment the rhdf5 package and
library but it seems to have vanished from either the CRAN or
BioConductors sites.
Can you tell me where it would be possible to find it or any R
library (or function) able to read hdf files?

Can R read NCSA's HDF?
I'm an R newbie, so please forgive if this question has been
asked and answered many times before on this mailing list. I
can't find anything in the manual (Notes or R), the FAQ or on
CRAN, so...
Has anyone implemented an interface so R can read NCSA's HDF?

R crashes on new laptop
The problem is that R crashes with an exception "R for Windows GUI front-end
has encountered a problem and needs to close..." It doesn't always crash,
but almost always does.
Thanks for any help (fixes, workarounds, or diagnostics) you can provide!

segfault when unloading a shared library
Hi All,
I'm still actively researching this problem (reading R-ext manual),
but I hoped that I might be able to get some additional insight from
the list given that I'm fairly new at writing R extension code.
Problem: I have some fairly simple code (.Call interface) that makes
a call to another shared library, which, in turn, calls routines in an
HDF5 shared library. The good news

Rapid Random Access
I have some code that can potentially produce a huge number of
large-ish R data frames, each of a different number of rows. All the
data frames together will be way too big to keep in R's memory, but
we'll assume a single one is manageable. It's just when there's a
million of them that the machine might start to burn up.
However I might, for example, want to compute some
