My data consists of numeric (yy) and categorical (xx) variables, as shown below.
> xx = c(rep("C", 5), rep("D",5))> xx [1] "C" "C" "C" "C" "C" "D" "D" "D" "D" "D"> yy = rnorm(10, 0, 4)> yy [1] 2.7219346 -3.7142481 6.8716534 -0.9352463 0.4901249 3.8113247 [7] -2.6602041 1.7714471 4.7298233 0.8848188
> xx1 = as.integer(as.factor(xx))> plot(xx1, yy, ylim = c(-13.5, 4), col="blue")
I have attached the plot above as plot1
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 (see plot1 attached).
How could I possibly go about this, let me know. Any help will be greatly appreciated.
Thanks in advance for your help,JN
