[R] Grouped Boxplot

[David Winsemius]

Back in March Soren Vogel asked exactly the same thing:

Here is the solution that was offered then. (He offered a dataset as  
requested in the Posting Guide.)  ... with only a minor adjustment:

g <- rep.int(c("A", "B", "C", "D"), 125)
t <- rnorm(5000)
a <- sample(t, 500, replace=TRUE)
b <- sample(t, 500, replace=TRUE)
dta <- data.frame(val = sample(t,1000), g = gl(4, 250, labels=c("A",  
"B", "C", "D")) , G2 = gl(2,1, labels=c("XX", "YY")))
boxplot( val ~ g + G2, data=dta, at = 0.8*c(1,2,3,4,6,7,8,9),  
boxwex=0.8)

This should have shown up with this:

RSiteSearch("grouped boxplot")
