Hi the list. I try to learn the S4 programming. I find the wiki and several doc. But I still have few questions...
1. To define 'representation', we can use two syntax : - representation=list(temps = 'numeric',traj = 'matrix') - representation(temps = 'numeric',traj = 'matrix') Is there any difference ? 2. 'validityMethod' check the intialisation of a new object, but not the latter modifications. Is it possible to set up a validation that check every modifications ? 3. When we use setMethod('initialize',...) does the validityMethod become un-used ? 4. Is it possible to set up several initialization processes ? One that build an objet from a data.frame, one from a matrix...
