AFAIK CRAN does not explicitly require use of a GPL license (though
obviously the license needs to allow at least free access to the
packages and source).
GPL and the other licences are about distribution. CRAN requires a
licence to allow it to distribute packages -- in some cases (e.g.
mclust) that requires a CRAN exception.
Copyright is an almost entirely orthogonal issue. In many countries
all intellectual creation is copyright -- this message is, R itself
is, my packages are (including my contributions to KernSmooth) -- and
that does not need to stated. Matt Wand has chosen to assert his
copyright in the startup message. A closely related concept you will
see in British books is that 'X has asserted his moral right to be
identified as the author of this work'.
With the freedoms that Open Source licences give goes a moral
responsibility to give due credit, something we see **far** too little
of here.

Hi all,
I'm not sure who to ask this, so I'm posting this here.
I just ran:
require(KernSmooth)
And got (I bolded the text):
Loading required package: KernSmooth
KernSmooth 2.23 loaded
*Copyright M. P. Wand 1997-2009*
Warning message:
package 'KernSmooth' was built under R version 2.12.1
What does that mean?
Well, I think that is just a warning that it was built under a
different version of R than you are currently running it under.
If memory serves, the current KernSmooth is a port to R by Brian
Ripley; that message suggests the original KernSmooth was copyrighted
by M. P. Wand from 1997 until 2009 (probably the original author in
S?).
Cheers,
Josh
Thanks,
Tal
