[R] Question about Factors

[Chris Li]

Hi all,

I am new to R and I have got a question in regards to factors.

Say I have a simple dataset like the following:

Name   Time     Value
a         1:00     1.25
a         2:00     1.26
b         1:00     1.29
b         2:00     1.28
c         1:00     1.21
c         1:30     1.20
c         2:00     1.23

I want to write a script that automatically plot value against time for a, b
and c. Because I have got more than 1 datasets, therefore the name of the
next dataset may consist d, e, h and g. So I will need a script that can
detect the changes in Name automatically.

Thank you very much for your time.

Chris
