____________________
What I want to do is a 2d-graph plot where I will have the name of the
student in the X-axis and the name of the lesson in the Y-axis and the
number from each pair will be used to construct the plot. I am newbie with R
and I don't know which package shall I use nor the commands with which I
will import my data in R so that the plot will be created...
