dnbinom(,size<1,)=0 (PR#842)
This came up on r-help but indicates a bug.
dnbinom(x,n,p) calls dbinom_raw(n-1,...)
which returns 0 for n<1.

Obtaining names of ``...'' arguments.
This may be an FAQ, but a (perfunctory) search failed to turn it up.
Suppose I have a function foo(...){<something>} and I want to obtain,
inside foo, the names of items comprising the ``...''. E.g. if I
call
foo(melvin,clyde,irving)
I want to be able to loop through the ``...'' and successively obtain
the text strings "melvin", "clyde", and

how to save an R object selectively?
Hi,
How to save an R object for example a matrix or vector and not all objects created in a session (which is usually performed by save.image or q("yes"))?

Documenting options specific to a package.
If one specifies new options in a package, using the options()
function, where does/should one document these new options?
E.g. suppose that I put the line
options(melvin=42)
in a file zzz.R in the R directory of the package source, where the
package contains functions foo(), bar(), clyde(), and irving() which
all query options("melvin") and take some action based on the value

scoping problem?
Dear R-helpers: (this is part of a bigger program)
the following fails as a function, but runs OK
if we comment out the fnfn_ function() line.
Any hint would be appreciated. -Yudi-

A rebel boxplot question
Dear R list members
I am trying to improve a boxplot with 2 data sets. I run somethinkg like
boxplot(data1 ~ month, add=F, col = "red", ...)
boxplot(data2 ~ month, add=T, col = "blue", ...)
The problem is that the data from February are missing for data2, so R
think that must take little more space between the data classes in data 2
and then both data gropus are not aligned.

PR#1132.
Just now I again had occasion to want nested describe lists in a
documentation file. I found that the bug which I reported on 18
October, 2001 still persists. I checked on the bug report at the R
web page, and found that the notes say ``Not a problem in R 1.4.0
(2001-12-08)''.
Well, it's still a problem for me --- using R 1.4.1.

Creating an environment for a function.
I am trying to build a function in a context where the environment
concept would appear to be useful. But I'm a bit foggy about this
concept and would appreciate some pointers and advice.
Basically the function I'm building, say foo(x,t), is a function of
two variables). Depending on the value of t, foo will return one of
the values f1(x), f2(x), ..., fk(x), where each of f1, ..., fk is

Simple 2-Way Anova issue in R

Puzzled about a new method for "[".
I recently tried to write a new method for "[", to be applied to data
frames, so that the object returned would retain (all) attributes of the
columns, including attributes that my code had created.
I thrashed around for quite a while, and then got some help from Rui
Barradas who showed me how to do it, in the following manner:

Three-way ANOVA?

I'm a biologist, so please forgive me if my question sounds absurd! I have 3

but i can only get stats from anova for the first 2 variables. The third comes
up as NA. The degrees of freedom for the third variable are 0.

help.start in R-1.7.0 with Netscape 7.0.
