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
Sounds like homework?! Anyway, see ?par and ?axis to answer your question directly or ?boxplot more implicitly... Best, Uwe Ligges
