similar to: best HDF5 package: h5r or rhdf5?

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

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

1. What does this have to do with R? 2. If it concerns computational biology, the Bioconductor Help list may be a better place to post.

This question is a clone of my stackoverflow question which never got answered (o_O). Therefore I am posting it here. I would really like some inputs if possible. I am currently building some applications which make use of HDF5 files. I have already taken a look at the hdfgroup website with regards to dataspace <https://support.hdfgroup.org/HDF5/doc/H5.user/Dataspaces.html> and I think I

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

--=-=-= Included below are: 1) Diffs to to remove HDF5 from R 2) Diffs to pass thru --with-* options to a module's configure script during "R INSTALL". (To reiterate a plea for this capability...) This applies only to Unix, the Windows (mingw32 in my case) build approach of passing in make variables like *-CFLAGS and *-LDFLAGS works fine. The only hitch

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

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'

*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: *

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 all, I'm trying to make an integer-backed quarter (as in fraction of year) class, but I can't quite it to work. I want integer-backed so I don't have to worry about floating-point effects when doing math, and so that I can use it as in data.table. First of all, is there a good reference for this anywhere? All of the S4 tutorials that I've found have been too high-level, and

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.

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

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

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

Dear R-user group I am currently running R-0.90.1-1 for LinuxPPC on my PowerBook. Few days ago I have seen at CRAN that a new R-package exists, namely R-base-with-hdf5-0.90.1-2. Sorrowly, I could not find any explanation, what the difference to the other package is. I have downloaded the "Introduction to HDF5 Release 1.2" from hdf.ncsa.uiuc.edu/HDF5. It seems that HDF5 is a data

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 ->

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

Is there any way to get the current memory used by R without running gc()? I'd like to include the memory usage in logging output, but calling gc() to get that information takes long enough to be noticeable (~ 6 s with ~ 20 GB of ram in use), which goes against the point of logging. Thanks, Johann
