R help - Apr 2011 - Vertical bwplot and stripplot

Hi,

I'd like to change the default orientation of bwplot() and stripplot()
so the plots are displayed vertically.  Passing horizontal=FALSE into
stripplot in the simple code below doesn't seem to be the answer.

library(lattice);
x <- rnorm(100);
y <- as.factor(sapply(1:100, function(k)
sample(c("A","B","C"), 1,
prob=c(1/2, 1/3, 1/6))));
my.df <- data.frame(x=x, y=y);
stripplot(~x | y, data=my.df, as.table=TRUE, layout=c(1,3), hor);

Many thanks for any suggestions!

Cheers,
Dave

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.)
