[Courses] Lesson-2 Update

[A. Mani]

I have added a supplement including useful commands for manipulating
data frames.
So you will need to use
http://courses.linuxchix.org/mod/resource/view.php?id=257
http://courses.linuxchix.org/mod/resource/view.php?id=258
http://courses.linuxchix.org/file.php/24/Lesson-2/kernel.csv
for Lesson-2

Part-B of this supplement will be added by ALB soon.

Best

A. Mani
