R help - Jan 2006 - How to produce this graphic

Hello there,

I would like to produce a plot of x<-c(4,5,6),which is the mean of each
group and y<-c('groupA','groupB','groupC'). 

plot (x,y) can not produce any graphics because y is not numerical. 

What should I do to produce this graphic?


Thank you in advance

One possibility:
x <- c(4,5,6)
plot(x, axes=F)
axis(1, c(1:3), labels=y)

or see ?bar.plot

dotchart(x,y) does a nice job.  See ?dotchart for a lot of optional 
arguments to change the look of it.
