R help - Nov 2007 - ftable as latex (with Hmisc?)

Dear List, possibly called Frank,

I tried to create an ftable lookalike of the following data set in LaTeX/Sweave
with summary(formula,..), but I could not get it to work for count tables; 
numeric tables work fine. 

summary(formula,...,fun="table") does not give the full cross
breakdown.

Other suggestions welcome. Note that in the output there should be empty fields
on repeated column values like ftable produces.

Dieter

library(Hmisc)
df = data.frame(drug=sample(c("P","V"),100,TRUE),
                Hist1=sample(c("Pos","Neg"),100,TRUE),
                Hist2=sample(c("Pos","Neg"),100,TRUE))
ftable(drug~Hist1+Hist2,data=df)

See if fun=table (no quotes) or method='cross' work for you.

... sample followed

Thanks, this works for most cases. I feared I had missed something in
summary(...,table).
