How to write an S4 method for sum or a Summary generic
...w to write a
generic function for Summary group generics which uses tail recursion to
allow the correct method to be called on each member of a ... argument list.
But it gives no examples of what individual method functions need to look
like. Any ideas or a place to look for working code?

qbinom when probability is 1 (PR#5900)
Full_Name: Jonathan Swinton
Version: 1.8.0
OS: Windows 2000
Submission from: (NULL) (193.132.159.34)
Calling qbinom with a sample probability of 1 returns NaN
> qbinom(p=0.95,size=10,prob=1)
[1] NaN
I believe that this is wrong and that qbinom(p,size,prob=1) should always be
size for 0<p<=1.

Old style and new style classes
...mmitted to by some active developers. Is this true? Do new style classes have an active future? Is R committed to them? Insightful?
I use old-style (S version3 engine) and new-style (S version4) classes in the sense of Venables and Ripley.

Rgui open script file selection filter wish
When using the File/Open Script.. dialogue on Windows, the list of filters
offered is
R files (*.R)
S files (*.q,*.ssc,*.S)
All files (*.*)
I wish that an additional filter be offered as
Sweave files (*.Rnw,*.Snw)
I find that the Rgui script editor is adequate for most of my R development
and tend to edit *.Rnw files there.

Problem building R from source on Windows

R on Tru64 OSF 5.1
Has anyone achieved a current successful build of R
1.8 or 1.9 or earlier for HPUX Tru 64 OSF 5.1?
There is no binary version of R for HPUX Tru 64 OSF
5.1. The R admin manual mentions that the native make
fails on "Alpha/OSF (aka Tru 64)" and gnu make must be
used instead. There are problems reported with
building R versions around 1.4 from 2002 on R-devel,
some of which were fixed with
