similar to: hdf5

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. There is just 1

Hi all, I'm testing the use of the hdf5 R library under Windows XP. With some simple example (an R list with several subobjects as showed in the examples in the library) the library exports and imports .hdf files adequately. However, if I try to open the exported file with another program (HDFView 2.5) I receive the message that the file is an unsupported format. HDFView 2.5 does not seems to

*Hi everyone, I am a new subscriber, so I hope I'm posting in the right way. I need to load a hdf5 file, so I installed the hdf5 libraries ad the hdf5 R package; in downloaded a small sample file from the hdf5 website and I could correctly load it. But when I try to load my file: * require(hdf5) rm(list=ls()) ls() hdf5load("my_file.h5", verbosity=3) *I get this error message: *

Has anyone succeeded in using HDF5 in R? Using Solaris R version 0.64.0: 1) R was configured in this way: cd /home/westley/R/R-0.64.0 setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:/home/westley/HDF/lib ./configure \ --prefix=/home/westley/R \ --with-g77=/usr/calspan/gnu/bin/g77 \ --x-lib=/usr/openwin/lib \ --with-hdf5-libs=/home/westley/HDF/lib 2) But, when I attempt to

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

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. -rw-rw-r-- 1 ftp 100 3416612 Oct 6 17:45 R-base-with-hdf5-0.65.1-1.i386.rpm -rw-rw-r-- 1 ftp 100 2300453 Oct 6 17:48

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: ftp://ftp.swarm.org/pub/swarm/src/testing/hdf5_1.4.7.tar.gz I prefer to use RPMs to maintain software across many linux

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 ->

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

The package works fine, but it seems not to provide access to fields, but only to the whole data in a certain file (function hdf5load(file, load = TRUE, verbosity = 0, tidy = FALSE)) Since hdf5 organizes the data and metadata in a hierarchical structure, we must explore in our problem (file>7GB), but it seems not possible with the functions in the package. Any suggestions? Please, let me know

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 source of the package

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 but got this message complaining it can''t find

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' --configure-args='--with-hdf5=/share/apps/HDF5'

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 cd hdf5-1.8.4

Hi there, I have a Java process that writes HDF5 files with the following approximate structure: group "xxx" { group "yyy" { dataset {} dataset {} } group "zzz" { dataset {} dataset {} } } where dataset is a rank one dataspace having a compound datatype defined as: H5T_UNIX_TIME, float, float, float, float I

Hello, I want to install hdf5 libraries for R and I get the same error as posted below whether I try install.packages("hdf5") from R command prompt or the command line installation below. I would appreciate if any one could help me on this. [alamj@thor hdf5]$ ./configure --with-hdf5=/bluejay/apps/HDF5-1.6.6/x86_64 checking for gcc... gcc checking for C compiler default output... a.out

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: * R 2.10.0 (x64) on Mac OS X 10.6 * hdf5 1.8.3 installed via macports * hdf5_1.6.9.tar.gz from CRAN I suspect the problem I am having relates to

I've used the HDF5 library to bring some data into R.

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 <- hdf5load("asi-s6250-20090704-v5i.hdf", load =

1. This relates to the package *rhdf5* and its implementation of the HDF5 dataspace interface. I am asking for an example of how other people who use this package make use of the HDF5 data space interface exposed by the library. Longer answer: As per my understanding, the dataspace interface exposes data locations within a dataspace, but even while retrieving data from an hdf5 file using methods
