Hi Gabor, Christian, R users!
I asked several days ago how to provide a signature in S4 for an existing function of
the type which gabor proposes.
There are already some functions in the base package which are using the syntax
sugested by you.
e.g:
rbind -
function (..., deparse.level = 1)
Hallo!
There is a package called BioSeq1 at bioconductor. It Is using the .C interface and
was doing a lot of string manipulation. Should have tons of examples.
The simplest way to do it is.
You my alloc fist the char in R.

This is a bad interaction of packages installed from debian with the R
update.packages() system.
Moral of the story is don't try to update.packges() for any of the

Hi,
I'm trying to use the usr argument but I see no effect of this option
on my plots. For example:
par(usr=c(0,4,0,4))
plot(1,1)
This plots one point fine, but the coordinates of the plotting region
are not those that I specified using par()...
I can check this with
par(usr)
[1] 0.568 1.432
Bonjour, Nicolas
par('usr') is read-only (see '?par')
That makes sense: user coordinates come from what you have plotted.
Would you show us an example of what exactly you want to do?

You could try something like this.
