R v2.1.0 patched (>2005-05-09) for Windows?
I'm trying to troubleshoot a case where R crashes on Windows. It does
not occur at all with my R v2.1.0 patched (2005-05-09), but happens on R
v2.1.1 (patched or non-patched) in many different cases. The R
v2.2.0dev (2005-07-15) also got this problem (although it won't crash on
the below example). I previously reported this

R CMD check --as-cran and (a)spell checking
Does anyone know if it is possible to add a dictionary file of known
words that becomes part of the *built* package to tell 'R CMD check
--as-cran' not to report these words as misspelled. I want this
dictionary to come with the *.tar.gz such that it will be available
regardless where the package is checked. For instance, currently I
get:

Call by reference: Was: Object orientation?
To reply to Yves Gauvreau question (Jan 24, 2001) about how to set values
within function, it is possible to do without without using the "<<-"
assignment operator or other nasty tricks. I had the same problem and I did
a nasty workaround two weeks ago implementing the functionality of reference
variables, but today I "ran into" the [R] help page for ".Alias".

Native implementation of rowMedians()
Hi,
I've got a version of rowMedians(x, na.rm=FALSE) for matrices that
handles missing values implemented in C. It has been optimized for
memory and speed. To avoid coercing integers to doubles, and hence
allocate an additional 200% memory, there is one C function for
integers and one for doubles.
The rowMedians() implementation is currently sitting in my non-CRAN

scan without line numbers?
When using the function scan(quiet=TRUE) the line numbers are printed.
Example:
> scan(quiet=TRUE)
1: 123 [ENTER]
2: [ENTER]
[1] 123
>
Is it possible to not show the line numbers? I know about readLines() but I
would like to be able to use the extra features of scan().
Thanks for you help!

R v2.1.1 for Windows and "non-reproducible" crashes
Hi,
R v2.1.1 patched (2005-05-26) for Windows crashes. The sympotoms are
like "memory leakage". The patched version from two days ago crashes at
a different position in R CMD check compared to todays version.
A "REPRODUCIBLE" EXAMPLE:
Unfortunately, I cannot create a minimal code example reproducing the
crash, but here is at least a simple way to reproduce it:

Minor bug in maketitle.pl (with bug correction) (PR#864)

R.oo inheritance with pass by reference
I thought I would post an example of using R.oo with inheritance and pass by
reference for future searches. With PerMore I am inheriting Person. Then I
am changing an object data memeber of an object of PerMore class using pass
by reference ('mimiced' by R.oo) in an object of AgeMultiplier. I change a
data member in the child class and the parent class for demonstration
purposes. This is

R.oo package: do setMethodS3 work upon construction
Hello (Heinrich),
I did not know I could do this. It doesn't seem to be documented anywhere.
Thought this would be helpful to the fraction of the community using package
R.oo. Note the call of a setMethodS3 method, xOne, in the setConstructorS3.
This is extremely useful if xOne (in this case) is a very complex method
(that you always want to be called every time you create a new object). If I

Title of bundled packages in the library index (PR#1017)
Full_Name: Henrik Bengtsson
Version: 1.3.0
OS: Windows Me
Submission from: (NULL) (216.175.122.171)
I realized that the title of packages in the library index when they are in a
bundle is the title of the bundle and not the package.
It looks like the TITLE file, which apparently is used for generating the
library index, takes the value of the bundle's title and not the package's
title.

R.oo package, inherit two classes
Hello,
How do I inherit two classes using the R.oo package. Below is kind of a
silly example, but I am trying to create class PerDog from classes Dog and
Person. Error at bottom. I've tried a few other ways of using extend(), but
nothing seems to get me what I want.
Example:
setConstructorS3("Person", function(age=NA) {
this = extend(Object(), "Person",
.age=age

R.oo data members / inheritance
If someone is able, can you tell me if there is a better way to do this?
More specifically, do I have to rewrite all of the data members stuff and
extend stuff of parent class in the child class? See below. Thanks in
advance!
Example 1:
setConstructorS3("ClassA", function(A,x) {
if(missing(A))A=15;
if(missing(x))x=NA;
extend(Object(), "ClassA",
.size = A,

Difficulties with R.oo (static fields, etc.)
I would like to use R.oo and tcltk to implement a Turtle World. I have
encountered
many problems because:
1) I am not sure how to implement static fields with R.oo
2) I am not sure how to implement a constructor that would
call a function only for the first instance of a class (i.e., to
initialize
value of static fields only once)
3) I am not sure how to remove/delete cleanly existing

R.oo: do work on data member at construction
Hello,
I'd like to 'do work' on data members upon construction (i.e. without
implementing it in a get method). Is this the best way to create data member
'z' upon construction? I'm thinking if .z=paste(x,y) below gets more complex
I'll run into issues.

Call super methods from inherited classes R.oo
Hi R-community,
I'm very busy with a software project which I would like to development
completely with R.oo. Many of the object oriented aspects that I already
know from Java development seems to be in place with this library.
But...there is something that I'm really missing... *the super method call*
Just a little example that shall demonstrate what I mean:
