[Since this question seems to be unanswered:]

This is a question related to Peter Dalgaard's book, so why don't you 
ask the author rather than the whole world?

Note that caff.materia is a matrix while as.table(caff.marital) is a 
table (and has a different print method).

Why does the justification matter here? I'm much too lazy to look for 
changes in R related to your question - but probably you have done 
yourself before asking the question...???
And why don't you cite the example you are referring to (e.g. by a page 
number!!!) exactly? I'm also too lazy to read Peter's book once more 
just in order to find the example you are talking about!
