hi,
Previously my email very simple and less information. Let say I have raw
data as below:-

user_id  website          time
20        google            0930
21        yahoo            0935
20        facebook        1000
25        facebook        1015
61        google            0940
60        yahoo            1050
40        friendster        1115
61        google            1200
40        friendster        1215
25        google            1030
28        youtube          0830
30        facebook        0945

This data described about particular website viewed by particular ID  in one
day.

My problem is how to sort the data? So that, I can get information about one
user_id viewed how many website perday?

secondly, I want to plotted above data where x-axis (user_id) and
y-axis(website).

Actually, im new to R-project and still in learning process. So, I really
want you all help.
Thank you and I really appreciate everyone feedback.

regards,
Hema.
