[R] boxplot with datapoint

[Yupu Liang]

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!
Yupu
