To all moderators i guess, my question was probably not clear this is not a homework, i am trying to understand R by doing some exercise in my book.
I will however participate a course in R in august and thought it could be good to have some
knowledge before. I hoped for help from you since i have no instructor to ask, that would have been
my first choice.
thanks anyway
Lotta
