clean programming
Hello the list,
I am trying to write a "cleanProgramming" function to test the
procedure I use. For example, I want to be sure that I am not using
globals variables. The function "findGlobals" detect that.
To list the globals used in function "fun", the syntax is :
"findGlobals(fun,FALSE)$variable"
My problem is that I want to use it in a function,

R 2.7 package.skeleton
Hi the devel list
I am testing package.skeleton in R 2.7 (download today). I get an error
that I do not understand. I guess it is not an error from my code since
I have no probleme when I source it. So is it a error in
package.skeleton?
Here is my code :

getGraphicsEvent plotting two graph
Hi the list,
I need to use getGraphicsEvent to plot two graph. On the following toy
example:
- the function b is ploting two graph depending on a parameter
- the function a is calling b according to some user answers. It is
suppose to call b until the user press Return, but it does not.
b <- function(x){
dev.off(2);dev.off(3)
windows();windows(3,3,xpos=0)
dev.set(2);plot(1:x)

package.skeleton does invalide regular name, bis... (PR#12020)
Hi the list,
I guess I find an other bug (the first one is at the end off this mail)
in package.skeleton. It occurs when we give as code_file some file that
are not in the current directories.
If we give a single file to code_file (like code_file=3D"riri/fifi.R"),
it does not reconize fifi.R as a regular name and change it to
riri/zfifi.R
If we give several file to code_file (like

Integer vs numeric
Hi the list.
I do not understand the philosophy behind numeric and integer.
- 1 is numeric (which I find surprising)
- 2 is numeric.
- 1:2 is integer.
Why is that ?

At the first stage I want to count how many people in the survey, how many

How do I do that?

Gower distance between a individual and a population

I need to compute Gower distance between a specific individual and all
the other individual.
The function DAISY from package cluster compute all the pairwise
dissimilarities of a population. If the population is N individuals,
that is arround N^2 distances to compute.

setClass question
I would like to add a class to the SparseM package. I have a class "matrix.csr"
that describes a matrix in compressed sparse row format, now I would like a class
matrix.diag.csr that describes such objects when they happen to be diagonal.
The idea is that matrix.diag.csr objects should behave (later in life) exactly like
matrix.csr objects, the distinction is only needed in order to

Is it possible to be sponsored by R?
Hi the list,
I am a member of the organizing comity of the French Statistics Association (SFdS)'s conference. We
are looking for sponsors. Some software (SAS, RITME, ...) are represented. Do you know if there is
any possibility to be sponsored by R (or by an association close to R)? Do you think I can ask to
the R fondation?

Compatibility issue between lme4 and kml (operateur "[")
Hi all,
There is a compatibility issue between the package 'lme4' and my package
'kml'. I define the "[" operator. It works just fine in my package (1). If I
try to use the lme4 package, then it does no longer work (2). Moreover, it
has some kind of strange behavior (3). Do you know what is wrong? Any idea
of how I can correct that?
Thanks for your help
