A) hor is not defined
B) it doesn't make sense to me to have the continuous variable as the  
independent variable here, despite if being named `x`.

Try:
stripplot(x~y , data=my.df, as.table=TRUE, layout=c(1,3),  
horizontal=FALSE);

(I didn't recognize the as.table argument, but experimentation seems  
to produce a top-down order to the plots.)
