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

Is there a GIF graphics device or some other way to generate a GIF from an R plot instead of postscript? Then, I could paste a plot right into PowerPoint or Word. -- Terry J.

Has anyone successfully installed ESS on Win95? I have emacs version 19.34.6 and R version 0.63.3. The ESS README and Makefiles seem pretty Unix-specific. -- Terry J.

Suppose you're reading data from a file in which the column names contain underscore characters. Example: ------ start of file ----- pos_x pos_y 1.0 0.0 2.0 1.0 ------ end of file ------- Using read.table, I can read this file just fine: > data <- read.table (file="data", head=T) > data pos_x pos_y 1 1 0 2 2 1 > However, I can't

In version 0.63.0 for Win95, I can use text() to write into the left margin (to the left of the axis) as follows: > plot(0:10,0:10,pch="+") > text(c(1,0.5,0,-0.5,-1),1,"O") I see 5 "O" symbols at the expected position, two of which are left of the left axis. However, in version 0.64.0 for Solaris 2.5.1 on a Sparc/Ultra2, I only see three "O"

Is there a way to read a file one line at a time? My file is potentially very large (multiple gigabytes) so I'd like to read and process one line at a time. The only choices I see are: 1) Direct the file to standard input and use readline(), but then I have to parse the data columns myself. 2) Call scan() with nlines=1 over and over again, incrementing skip, but I suspect that it will

I need to build R (we're currently at R version 0.64.0) for Solaris 2.5.1 on SunSPARC without using the libF77.so and libsunmath.so shared libraries. I'd like to use statically linked libraries instead. Nothing I have tried has worked as measured by executing the command "ldd R.binary" to see whether it references the shared libraries or not. This is what I've tried: 1)

1) Is it possible to erase data points, legends, and/or text from an R plot? 2) What's the best way to find the closest data point to what locator() returns? For more background and some context on these questions, read on... In using R interactively, I am displaying further details about a specific data point when the user clicks on the plot point. Here's a simple example: #

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

Is there a way to measure the length of a character string as text() or mtext() would display it? Not in characters, but in inches or user coordinates. I'm displaying a hierarchical list in the left margin. I'd like to determine the length of the labels so that I can resize the plot so the labels don't spill over into the plot area. Like this:

I've a plot which puts some text and lines in a wider than normal left margin (using xpd=T). When I use dev.print() to capture the plot to postscript, it faithfully duplicates the plot except for the graphics in the left margin. I can't duplicate this effect in a simple plot such as plot(runif(10)), so I can't give you sample code. Any idea what I'm doing wrong? R version

When running R in batch mode, I would like to detect certain errors and prevent them from terminating the script. Specifically, when I read in a file with read.table() and the file is empty, the script terminates. There are occasions when an empty file is OK, so I'd like to continue running. How can I catch such errors? -- Terry J. Westley, Software Systems Engineering Supervisor Veridian

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 =

I've installed hdf5 [library & includes] here locally, last week. [see ?hdf5save in R] There is a remaining compilation / linking problem for me: The hdf5 library uses "compress2" a routine defined in Gnu's zlib, but not available in the zlib that comes with X11R6.3 (which we have installed). Now unfortunately, the final link statement for R (0.65) [for me, with hdf5

Hello everybody, I'm using hdf5 files to store results from intermediate calculations. These are usually part of a list, called "res". As I want the hdf-files to contain all the members of res in its top "directory", I used to do attach(res) do.call("hdf5save", args=c(fileout=file.path(dir, ofile), as.list(names(res)))) detach(res) which did what I

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

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
