This should be doable in the development version of Lattice. There is an 
example in example(xyplot), and it's exactly as you would expect (I hope);
i.e, you would get  vertical bars if you do 


where x is a factor/shingle/character vector and y is numeric. 
If you really want this when x is numeric, you have to additionally give

barchart(y~x, horizontal = FALSE)

One issue is how to write the levels of x on the x-axis. If the labels are 
long, I would suggest either 

scales = list(x=list(rot = 90))


scales = list(x=list(abbreviate = TRUE))
