",sep="",header=TRUE)

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.
