You have missed the point completely.
There is no way you can use the same command on a Unix-alike and Windows,
so using system() in packages always needs to be conditionalized on OS.
If you want to use a shell on Windows, use shell(): you can even use bash
with it (but startup will be really sl

One can use the R shell on Windows:
shell("echo foo.bar | findstr foo")
or an explicit call to the Windows cmd console:
system("cmd /c echo foo.bar | findstr foo")

Hi, Anna. You
With cygwin bash installed under Windows, one can use pipes in system(),
e.g., like this:
R 2.5.0 under Windows XP:

foo | sed s/foo/bar/
> # but using 'bash -c' does:

Hi,
If I have warnings converted to errors, and if I plot a simple plot and
then resize and move the plot's window many times, I eventually get an

You could add a configure script to your package to detect the
availability of the tools you want to rely on.
On package load, you could try a simple call and determine whe

Oh, dang, and I know you had in fact told me about this befor
The first comment is that will only work on Unix-alikes, since '|' needs a
shell.
So, if this is on a Unix-alike you need to establish if the program is in
the path at run time and cache the result. I have no idea if this would
actually work, but for example system('gp --version') might provid

Quite often I need higher precision, or larger numbers,
than IEEE double precision allows. One strategy I sometimes
use is to use system() to call pari/gp, which is not constrained by
IEEE.
[pari/gp is a GPL high-level mathematical programming language
geared towards pure mathematics]
See ?suppressMessages
I did:

and saw no messages at all in 2.5.0. (And that is one of the noisiest.)

I tend to run batch jobs via littler. These often start with a single line
loading one or two in-house packages. Now, most the Depends of these
in-house packages now use Depends: entries in DESCRIPTION, rather than
require() in R/zzz.R. This seems to have at least one undesirable side

Dear R-Devel subscriber,
I encountered the following problem for tex-formatted table with xtable().
Suppose I do want the following matrix as a table in LaTeX:

Hello,
I am often asked how to filter lines from a data frame, like for example
get all the Mazda cars from mtcars, so that usually does the trick:
R> mtcars[ grep("Mazda", rownames(mtcars)) , ]
but, what about using a formula in `[.data.frame` to make that sort of
code meaningful:
# rownames
27 matches
