Subject: [R] plot graph by first letter


Hi all, may i know is it possible to plot a graph by first letter?

for example: 


Name:                      Age:

Angel                        20

Amelia                      20

Bernard                   19

Stephanie               20

Vanessa                   22

Angeline                  23

Camel                       21


If I want to plot the name started with letter 'A' and their Angel, how is

it possible to plot it?

Thanks.
