So what? Time to do your homework, isn't it?

phi: it is the same as pearson for a 2x2 table of dichotomous/binary 
data. Should be written in any basic textbook on descriptive statsitics. 
Do your homework!!! I really dislike these triple exclamation marks.

nominal: Well, try factor() or as.character(), or whatever .... depends 
on your aims....

Who are you? "Adolf Pessernig", or "nicole.raschun"???
