plotting numeric v. factor variables

Hi Bessie,

library(lattice)
x <- rep(1:3, each=20)
y <- rnorm(60, x)
x <- c('level1', 'level2', 'level3')[x]
stripplot(y ~ x)

# or perhaps

stripplot(x ~ y, jitter=TRUE)

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
