 
  
  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,

JN
