Hi,
I'm reading up on S4 classes *). There seem to be at least two ways of input
validation:
setClass() (using the 'validity' argument) and setValidity(). Is it a matter
of taste which function is used? Or should more complex validation code better
be put in a setValiditity call?

And, inside those validity checks, is most of the checking done with 'if'
'else' computations, or is it also common to use except()?
Cheers!!
