New methods for generic functions show and print : some visible with ls(), some not
Dear all,
I'm trying to understand the S4 way of object-oriented programming, but I
still can't grasp completely what R is doing. I have a class definition for
a class called PM10Meteo, and I set a initializer function. next, I include
a show method and a print method as shown below.
setClass( Class="PM10Meteo",...) # end setClass

strange behaviour of callNextMethod in S4 methods
Hello,
I experienced a strange behaviour of callNextMethod when used in either
initialize or any other S4 function method definition.
Help says callNextMethod calls the next inherited method for the current
function from where it is called with the same actual (non missing)
arguments. This is OK. The problem appears when some formal arguments
(in particular, S4 objects) of this function are

How to trigger a resync of a newly replaced empty brick in replicate config ?
Hi,
I simplified the config in my first email, but I actually have 2x4 servers in replicate-distribute with each 4 bricks for 6 of them and 2 bricks for the remaining 2. Full healing will just take ages... for a just single brick to resync !

S4 classes and debugging - Is there a summary?
Dear all,
I'm getting more and more frustrated with the whole S4 thing and I'm
looking for a more advanced summary on how to deal with them. Often I
get error messages that don't make sense at all, or the code is not
doing what I think it would do. Far too often inspecting the code
requires me to go to the source, which doesn't really help in easily
finding the bit of code

Reading data from a worksheet on the Internet
Dear R-users,
I have to read data from a worksheet that is available on the Internet. I
have been doing this by copying the worksheet from the browser.
But I would like to be able to copy the data automatically using the url
command.
But when using "url" command the result is the source code, I mean, a html

I see that the data I need is in the source code but before thinking

lattice custom axis function -- right side margins
Dear R help list,
I have a plot with two different vertical scales that I want to display
on either side of the plot. It's quite similar to the
Fahrenheit-Centigrade example in the examples section of the
documentation for axis.default.
The right-side axis is clipped off, though, and I haven't been able to
figure out anything with viewport() and clipping or trellis.par.set to

Creating S3 methods for S4 classes (coming from r-package-devel)
Dear all,
I asked this question on r-package-devel but Martin Maechler pointed out
this was more suited on R-devel. So here it goes:
per the manual, one should create and register both the S3 and a S4 method
if one needs a method for an S4 class for a function using S3 dispatching.
This is cumbersome, and not very optimal.
I was wondering if there's a better way to do this. Currently I

How to trigger a resync of a newly replaced empty brick in replicate config ?
You do not need to reset brick if brick path does not change. Replace
the brick format and mount, then gluster v start volname force.
To start self heal just run gluster v heal volname full.

dubious behaviour of match.arg() with nested functions.
Dear all,
I initially ran into this problem while rebuilding a package dependent on
nleqslv. I got the following error:
Error in match.arg(global) : 'arg' must be of length 1
This didn't occur in previous versions of nleqslv, but did in the current
one (2.4). I think I pinned the problem down to the following example:

use of random and nested factors in lme
Dear all,
I've read numerous posts about the random and nested factors in lme,
comparison to proc Mixed in SAS, and so on, but I'm still a bit confused by
the notations. More specifically, say we have a model with a fixed effect F,
a random effect R and another one N which is nested in R.
Say the model is described by Y~F
Can anyone clarify the difference between :
