Hi

your example code is not reproducible.

different length of aa and bb

x<-rnorm(20)
y<-rep(c(10,20),each=10)
bbb<-boxplot(x~as.factor(y))

although it seems as boxes are drawn at 10, 20 they are not. Actually the x position of each box is located at

• from help page - at numeric vector giving the locations where the boxplots should be drawn, particularly when add = TRUE; defaults to 1:n where n is the number of boxes.

as you can clearly demonstrate by issuing

points(1,0, cex=10)
