recursive data-structures in R - An S4 "node" Class
Hi,
In an effort to learn S4 objects, I am trying to port some c based tree
code to S4 object. My immediate goal is to use .Call() interface for
calling my c code from R. My long term goal is to understand how to write c
structs that follows S4 classes and not the other-way-around.
The c struct for the node is :
typedef struct node{
int c;
int n;
inode **nodes; //length = n
} inode;

setIs and method dispatch in S4 classes
Dear all,
I have a question regarding setIs and method dispatch in S4 classes:
Consider the following example:

setClass("A02", representation(a="numeric",d="numeric"))

Colors in interaction plots
Hi,
I am trying to plot an interaction.plot with different color for each
level of a factor. It has an erratic behavior.
For example, it works for the first interaction.plot below, with the
example from the ALDA book, but not with the other plots, from the NPK
dataset:

How to obtain the coefficients from a summary of aov ?
Dear Madame, Dear Sir,
I am able to obtain the coefficients from a 'summary' of 'lm', but NOT from a 'summary' of 'aov'.
The following example shows my steps.
## Initialize
rm(list = ls()) # remove (almost) everything in the working environment
utils::data(npk, package="MASS") # get data
model <- yield ~ block + N*P*K
## Using lm

Problem with proj
Hi all,
Perhaps this in an inappropriate post, but I've found a bug in proj
I'd like to track down a bit further before making a formal bug report.
The example below shows the problem, if you change the rownames proj
fails. The problem seems to be that there is a mismatch in the rownames
in the qr objects constructed by aov and the rownames that proj is
expecting them to have.

Help
Hello Everyone,
I am trying to excess the inbuit .Fortran and .C codes of R. Can any one
help me in that. For example in kmeans clustering the algorithms are written
in .Fortran I want to access them and see the .Fortran syntax of the codes.
Can any one help me how can I do that?
Thanx,

model.tables and NA?
Hi,
This might be a minor bug, or it could be that I'm just mis-using the tools
(again).
If you modify the example for model.tables to introduce an NA,
N <- c(0,1,0,1,1,1,0,0,0,1,1,0,1,1,0,0,1,0,1,0,1,1,0,0)
P <- c(1,1,0,0,0,1,0,1,1,1,0,0,0,1,0,1,1,0,0,1,0,1,1,0)

I'm baffled. When I run make check after installing from source, I

S4 - inheritance changed by order of setClassUnion and setAs()
Dear colleagues,
there is a behaviour with S4 (virtual) classes that I find very hard to understand: Depending on the position
of setAs(), the tree of inheritance changes.
This is my baseline example that defines the classes "grandma", "mother", "daughter" and a virtual
class "mr_x". For a new instance if "daughter", "mr_x" is betweeen

unary class union of an S3 class
Hi,
Short story
-----------
setClassUnion("ArrayLike", "array")
showClass("ArrayLike") # no slot
setClass("MyArrayLikeConcreteSubclass",
contains="ArrayLike",
representation(stuff="ANY")
)
showClass("MyArrayLikeConcreteSubclass") # 2 slots!!
That doesn't seem right.

interpretation of lm
Dear statistitians / R users,
I was told to analyse the effects of the four factors
using lm or update for aov. The following is the
result from lm. As you can see that in the last few
lines enclosed coefficients.
1)Does this mean I can write a formula, like
yield =0.26 + 0.03*H + 1.48*T + 0.04*L + 0.004*C
2) in the two levels design, is there any difference
between I use (-1, 1) to

model.tables call fails with "Error in inherits(object, "formula")"
Hello,
I noticed that model.tables fails when applied to an aov() fit if called
inside a function. The problem seems to occur when as.formula is used
inside a function on a string containing
"<formula> + Error( x / y )"
The reason I tried to use as.formula is to generate dynamic calls to aov().
Here is a minimal example illustrating the problem:

Image Processing packages
Hi,
I've been looking for Image Processing packages. Thresholding, Edge
Filters, Dct, Segmentation, Restoration. I'm aware, that Octave, Matlab
etc. would be a good address but then I'm missing the "statistical
power" of R. Does anybody know of packages, projects etc. Comments on
wether the use of R for such matters is useful are welcome.

Is it possible to simply the use of NULL slots (or at least improve the help files)?
Hi Martin,
Thankyou for your response.
I suspect that we're not going to agree on the main point.
Making it trivially simple (as say Java) to set slots to NULL.
So, I'll move on to the other points here.
