"registering" a generic method for a class
Sorry in advance if this is too simple a question, but I'm stuck with
some odd behavior and I can't find the text to rid myself of this
(admittedly somewhat trivial) problem. Note that I've done generic
programming with S3 "objects" in the past, but I've never really
dabbled in creating S4 objects until now.
So, I've created a new S4 class, call it

Dots argument in apply method
Hello everyone,
I'm working on a package using S4 classes and methods and I ran into the
following "problem" when I tried to create an "apply" method for objects
of one of my new classes. I've found a way around the problem but I
wonder if I did not paint myself into the corner. I'd like your opinion
about that.
So I have an object "myObj" of class

Caching bug with showMethods?
showMethods isn't reporting inherited methods when it is first
called. The methods are there and after calling them, showMethods
gives the right output.
Here is an example (using R-devel r39647):
setClass("A", representation(x="numeric"),
prototype=list(x=1))
setClass("B", contains="A",
prototype=list(x=2))

S4 method dispatch and namespaces: why is default method selected
Hi,
I ran into the following peculiarity involving S4 method dispatch and
namespaces.
I develop a package which have a namespace and which depends on 'pixmap'
package, which itself does not have a namespace.
Now, in my package I have a class which has a slot for objects from
class "pixmap" and I
want to have a "plot" method for this new class. Not to clutter the

function showMethods and inheritance
Hi,
The following question might come from my (deep) misunderstanding
of the concepts in the package 'methods'.
I have a class 'A', and a class 'B' inheriting 'A' (so defined
with 'setClass' and the parameter 'contains="A"'. The class
A has a method 'mymethod'. A call to 'showMethods("mymethod")'

Thank you, Andrew - I hadn't done so. (In a good way, I haven't yet had
problems with samba that have caused me to delve quite so deeply into the
DB :) so I'm not as familiar with the range of tools as I could be, sorry!)
This has flagged up quite a few errors, all along the lines of:

problem with Rscript
Hi all, this is probably some tricky configuration file problem, but I
figure someone here might have come across this in the past:
In short, I've been using Rscript to run my scripts, usually
successfully. But recently I've run into a strange problem, and the
only function that causes an error is "print".
I can create a file that contains only a print command, and it causes

Reference classes: accessor functions via 'getRefClass(...)$accessors(...)'
Hi there,
I''d like to choose between an "static" and "dynamic" access of a reference
class field, say ''a''.

Static: myObj$a
Dynamic: myObj$a.get() where the function retrieves the data

Help! Big problem when using "browser()" to do R debugging?
Hi all,
Could you please help me?
I am having the following weird problem when debugging R programs
using "browser()":
In my function, I've inserted a "browser()" in front of Step 1. My
function has 3 steps and at the end of each step, it will print out
the message "Step i is done"...
However, after I hit <ENTER> when the program stopped before Step 1

Hi the list,
I am defining S4 objet. Is it possbile to define a method that change
the slot of an object without using <- ?
My object contain a numeric and a matrix. At some point, I would like to
impute the missing value in the matrix. So I would like to use something
like :

diff of two timestamps
Hi all,
I have the following problem: I have a csv-file consisting of timestamp
values (no dates), e.g.:
Timestamp1;Timestamp2;
05:24:43;05:25:05;
15:47:02;15:47:22;
18:36:05;18:36:24;
15:21:24;15:22:04;
I need a vector with the difference of the two timestamps, so I read the
data with the read.csv-function:
myObj <- read.csv("file.csv",header=TRUE,sep=";").

seeing an S4 method, not using it
Dear list,
here is a problem I met when trying to use a method for an S4 object,
without loading the package in which the method was defined. I do not
know if this is a bug, or a mistake of mine. Normally, I think the
package in which the appropriate method is defined is loaded
automatically when calling the method. The problem is that if the
package is indeed loaded automatically, the

Huge performance difference between implicit and explicit print
Hi all,
Can anyone help me understand why an implicit print (i.e. just typing
df at the console), is so much slower than an explicit print (i.e.
print(df)) in the example below? I see the difference in both Rstudio
and in a terminal.
# Construct large df as quickly as possible
dummy <- 1:18e6
df <- lapply(1:10, function(x) dummy)
names(df) <- letters[1:10]
