I thought I would play around with the splines library a bit to see if
some of the extensions that Bill Venables and I created would fit in.
Right now I am having problems loading the library because the R code
uses := for assignment.  Should that be changed to <- now that the
code is a part of a library?
 R> library(splines)
 Error: couldn't find function ":="
 R> library("splines")
 Error: couldn't find function ":="
 R> bs
 Error: Object "bs" not found
 R> library(survival4)
 Autoloading required library: splines 
 Error: couldn't find function ":="

If you are interested in the Debian Linux packages, check a CRAN
(Comprehensive R Archive Network) site in the bin/ix86-linux
directory.  One such site is
		   ftp://franz.stat.wisc.edu/pub/R

Are we going to follow in the tradition of Java Beans and create an
concept of CRAN Berries?

Yes -- I thought it had all been changed by now.  

The second R release to provide libraries also ensured that their contents
automagically went into the system environment.  In R0.50 R&R have finally
removed the unnecessary := statement, forcing us to catch up and fix our 
libraries.

I hope so.  The idea reminds me of a cross between one of my favorite
packages/gui's (ViSta, and the icon map/guide map) and a nifty
program, LabView (if you aren't familiar with it, it is a
drop-and-drag program for designing lab measurement and data analysis 
(from the lab measures) -- just "connect the dots" to form a new
collection/analysis tool for recording lab data...).

(for those of you not familiar with java beans, they are reuseable
software components designed to be worked with visually through a gui,
rather than "programmacally").

But it's a long way off :-(.

best,

Yes, `:=' is gone now, and should be `<-'.

I've updated the corresponding library sources and the Debian GNU/Linux
package.  The new versions should appear on any CRAN site by tomorrow.
