[R-sig-eco] plotting numeric v. factor variables

[bessie green]

Hi.  This seems like it should be really obvious but I haven't been  
able to find a way to do it.

I want to plot some data so that i have 3 levels of a factor variable  
on the x-axis, and then numeric values for the response variable on  
the y-axis.  This would be a plot that is similar to a boxplot with  
the data points showing on it, except without the box and whiskers.   
Is there a plotting function in R to do this?

thanks,
bessie
