R help - Dec 2011 - plot mixed variables

My data consists of a numeric (yy)
  variable and a categorical (xx) variable, as shown below.
  
 


xx c(rep("C", 5), rep("D",5))

yy = rnorm(10, 0, 4)

xx1 as.integer(as.factor(xx))

 

plot(xx1, yy, ylim c(-13.5, 4), col="blue")

 

I
wish to generate a scatter plot of the data such that instead of 1 it prints C,
and instead of 2, it prints D on the x- axis.

 

Could
someone help me with an R code on how to go about this. Thank you in advance
for your  help,

plot(xx1, yy, ylim = c(-13.5, 4), col="blue", xaxt="n")
axis(1, at=c(1, 2), labels=c("C", "D"))

Defining your own axes with axis() offers a great deal of flexibility.

And thank you for providing a small reproducible example.
