R help - Nov 2007 - boxplot with datapoint

Hi,

I'm using boxplot in R to show box-whiskers plots for about 15  
categories of data.  I'd like to display ALL of the data points--not  
just the outliers.  Does anyone know if there's a parameter setting  
that will accomplish this with boxplot?  Other options would be to  
overlay the plotted points on top of the boxes?

Thanks a lot!

I think you will want to overlay the points. E.g.:

x<-rnorm(30)
y<-factor(rep(4:6,10), labels=LETTERS[1:3])
boxplot(x~y)
points(y,x)
