Storing and managing custom R functions for re-use
Dear all,

know how to deal with that.
this relationship doesn't seem to be strong, but it's my first time to see
something like that, and would like to know what to do if one day it becomes
stronger. I tested just for fun some

S-code for piecewise regression
Dear R-helpers,
a S-code for piecewise regressions was provided by Toms & Lesperance
(2003) Ecology, 84, 2034-2041 (paper can be found on the web).The code
is quite complete with different types of transitions around breakpoints
and model selection fonctions.
It doesn't work directly under R due to some "translation" problems I
guess. However I reckon that it would be a
