Hi everybody,
next week is the week when mentoring organizations can
apply for the Google Summer of Code. As I already wrote
in my first mail, the idea is to submit our ideas by
March 10.
Currently three ideas are on the list[1]:

I like the idea of median and friends working on ordered factors. Just a
couple of thoughts on possible implementations.
Adding extra checks and functionality will slow down the function. For a
single evaluation on a given dataset this slowdown will not be noticeable, but

Dear Greg,
thank you for your comments,
as Prof. Ripley pointed out, in the case of even sample size the
median is not unique and is formed by the two central observations or
a function of them, if that makes sense.
Dear Prof. Ripley,
thank you for your concern,
may I notice that (in case of
Yes I have discussed right continuous, left continous, etc. definitions for the
median in numeric data. I was just curious what the discussion was in texts
that cover quantiles/medians of ordered categorical data in detail.
I do not expect Low.5 as computer output for the median (but
Some modifications have been committed for the r-devel version today
that modify (essentially, correct a bug in) the communication of objects
to an S3 method from an S4 class that extends the S3 class.
This is one of a sequence of changes designed to make S4 classes work
more generally and
Like a couple of other posters in the past year, I was seeing R 2.8.1

Traceback:

Can you show us the output you get from building foreign, and explain
how it comes to be linked against libavl? I get (SunStudio 12)

The syntax for returning multiple arguments does not strike me as
particularly appealing. would it not possible to allow syntax like:
f= function() { return( rnorm(10), rnorm(20) ) }
(a,d$b) = f()
FWIW, my own solution is to define a multi-assign operator:
'%-%' -
I built it several times with a variety of flags and compilers.
Here's what was used for the gcc3 build:

Interesting, thanks. So
1) This is a shared R library build (not the default, and AFAIR no one
reporting this has mentioned that -- not you, for example) and
2) You have a third-party libintl.
One solution would seem to be to ask R to use the libintl in the
sources by (I think)
