using text() to write into left margin
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"

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?

measure displayed size of a character string
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.

need help with building R on Solaris without using shared FORTRAN libraries
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:

dev.print() doesn't copy graphics in left margin
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?

Problem loading hdf5 file
*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())

GIF graphics device
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.

using R interactively
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.

Fixing the HDF5 package: the on.exit mystery
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

using underscore character in column names
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

how to read a file one line at a time?
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

Problem with package hdf5-1.4.7 in R-1.7.1
Hello:
Has anyone successfully installed the package hdf5-1.4.7 in R version
1.7.1? I get a fatal error with a core dump (see below) whenever I try
to use hdf5load.
Since I'm in the process of moving to a new machine, I'm not sure
whether this is due to (my installations of) the HDF5 libs or the hdf5
package for R. Just for the record, the HDF5 data files were correctly
generated in the

need help installing ESS on Win95
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.

hdf5 package
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

errors terminating script
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?

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

Package HDF5
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

hdf5 package segfault when processing large data
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
