Hi Sarah:

Thank you very much, but my problem remains. What I want is not duplicate the sample, but be able to divide each frequency for a factor(specific for each value).For example:

Values           1      2     3    4     5
Frequency      10   34   56   67   98
Factor           105   50   60  150  200

Actually Im plotting: plot(Values, Frequency/Factor, type="b"). But I dont know how to visualize the probability distribution. On the hand to modify the "hist" function to include this Factor seems to be a daunting task.

any other advise will be welcome

thank you

m.
