hello, I have a problem to open an hdf file. i have downloaded the package 'hdf5' as it was advised on R seek. But when i try to load the file, the R console sends me an eror message: setwd("C:/Documents and Settings/Karine/Bureau/data/") #install.packages('hdf5') library("hdf5") sea_ice <- h...

Dear R Users, How do we read netcdf / hdf format files in R ? Also, can we convert netcdf to hdf format in R? Great Thanks, Best Regards, Yogesh [[alternative HTML version deleted]]

Dear All, I have data in HDF file format and would like to read it into R. I have tried the package hdf5 without success. Any ideas and suggestions??

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...

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 research instruments we are designing. I w...

Hi all -- I am working on 64-bit Windows XP. I'm not a very technical person when it comes to the command line stuff, so please forgive me if this is a stupid question. I have a bunch of HDF files, and I want to dump a single PM25 data layer from each file to .txt by invoking ncdump.exe from system(). Here's a sample command string: "C:/ncdump -v PM25 C:/01aug2010.hdf > C:/01aug2010.txt" This works perfectly in Python, but does not actually generate the .txt file in...

Hi, Is there a version of the hdf library for windows? Cheers Toby

...t 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 domain member fileserver. On the data share are several HDF files that we try to read into a couple of different applications on XP. I'm using the Compaq Array Visualizer just to look at them. The files on the server are owned by root, and world read/writable. As a regular user on the XP client, if I look at one of the files that's ~30MB in size, I&...

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? Sincerely, Nicolas Degallier UMR 7159 / IRD UR182 Laboratoire d'Oc?anographie et...

Hi, I saw some ref to R on HDF site and found some e-mails regarding them on Feb. Has there ben any developement on either of these software (HDF or netCDF)? I am primary interested in NT side, but Unix side will help to some degree. Thanks much in advance, ************************************************************** S. H...

...ding 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 is that everything works (the expected value is returned from the HDF5 call); the problem is that R segfaults when I unload the library. I initially suspected that the HDF5 function might be corrupting the stack/heap, however, if it is, it's not obvious to me....

...r I might, for example, want to compute some averages over the elements in the data frames. Or I might want to sample ten of them at random and do some plots. What I need is rapid random access to data stored in external files. Here's some ideas I've had: * Store all the data in an HDF-5 file - problem here is that the current HDF package for R reads the whole file in at once. * Store the data in some other custom binary format with an index for rapid access to the N-th elements. Problems: feels like reinventing HDF, cross-platform issues, etc. * Store the data in a numb...

Hi, I cannot seem to find a good answer for what I am doing wrong; I am simply trying to rsync a directory from one large disk partition to another disk, both ext2, on the same physical system by using the command: rsync --archive -v /etc /mnt/hdf/ I systematically get the following errors: # rsync --archive -v /etc /mnt/hdf/ building file list ... done etc/ etc/mtab etc/ntp/drift etc/vmware/vmnet8/dhcpd/dhcpd.leases etc/vmware/vmnet8/dhcpd/dhcpd.leases~ write failed on etc/mtab : No space left on device rsync error: error in file IO (co...

The basic question is: How can I pass configure script command line flags from the R CMD command? 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). I understood to install packages the following way: as root# R CMD INSTALL hdf5_1.4.7.tar.gz Installing source package `hdf5' ... checking for gcc... gcc checking for C compiler default output.....

So that we could explore the structure of a HDF5 file? Thanks a lot! [[alternative HTML version deleted]]
