I have an external process that is listening to and responding on a
port. This is working fine. If the external service is not running,
though, read.socket does not return and I do not see a way to
interrupt it. Is there a general way to deal with this situation to
have a timeout or of testing a
A simple question, I hope I have a binary file format that I want to
slurp into R using readBin. There are a couple of fields in the file that
are 4-byte floats. Since R has no "float" data type (4-byte), I am
wondering how to go about this task. I could simply do all the work in C,
but the

On our local cluster, users relatively routinely crash the head node
by doing simple and silly things that inadvertently eat all memory and
crash the head node. I read a bit about memory limits, but I am still
a bit unclear as to whether memory limits can be imposed a the R level
under linux. Cur

There are numerous tools like scons, make, ruffus, ant, rake, etc.
that can be used to build complex pipelines based on task
dependencies. These tools are written in a variety of languages, but
I have not seen such a thing for R. Is anyone aware of a package
available? The goal is to be able to
This is hopefully a simple question. I am trying to escape single
quotes like so:
abc's >> abc\'s
However, I cannot find an easy way to do that with gsub:
gsub("'","'","abc's")
# returns "abc\\'s"
How can I get a single \ in the output?
Thanks,
Sean

Thanks, Jim. That does it.

I have started to use Sweave to prepare reports for "end-users" of
statistical analyses. For these users, there is not generally
interest in the code used to accomplish the analysis, but only the
results. However, sometimes I would like to prepare the same
document, but with code chunks echoed, f

We have spent some time setting up Sun Grid Engine and OpenMPI on a
group of linux boxes. I have created a parallel environment and
everything seems to be working. I have Rmpi 0.5.5-5 installed on all
machines. I would like to start an interactive R session using, say,
8 processors and then star
Is there a way to make SVG files containing links (for use in a
browser) using any of the R graphics packages or devices?

I have been looking a bit at docbook as an alternative to latex.
However, Sweave is a very nice way to deal with documents mixing R
code, figures, and text as well as markup. I saw a couple of

No, I haven't gotten things to work. Even under openmpi without SGE,
I have R crashes on a regular basis when using Rmpi-0.5.5, so I
haven't really pursued it further.
