[R] plot graph by first letter

[arun]

Hi,

Try this:
dat1<-read.table(text="
 Name                      Age
 Angel                        20
 Amelia                      20
 Bernard                  19
 Stephanie              20
 Vanessa                  22
 Angeline                  23
 Camel                      21
 ",sep="",header=TRUE)
 dat2<-dat1[grepl("[A].*",dat1$Name),]
 dat2
      Name Age
1    Angel  20
2   Amelia  20
6 Angeline  23

rownames(dat2)<-1:nrow(dat2)
#Now you might be okay to plot.

?plot()
A.K.

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.
