I have a data.frame containing survey data that is already organized like a table:

> foo

           Excellent Very Good Good Fair Poor Very Poor
Question 1         8         7    3    0    0         0
Question 2         5         5    7    1    0         0
Question 3         7        10    1    0    0         0

> class(foo)

[1] "data.frame"

I would like to make a barchart (or stripplot) with three barcharts, one for each row in the data.frame foo. It seems like I have to coerce foo to class table to use with barchart.table in lattice but a simple as.table yields no fruit. Any help appreciated.
