box-whisker plot from pre-summarized data?

Hello,

Although my summary descriptives are generated outside of R (dataset is
huge), I would like to produce a box-whisker plot using bxp or perhaps a
function from the ggplot2 library using the precomputed summaries.

You should be able to do it like:

+ geom_boxplot(aes(ymin = lower.whisker, lower=lower.hinge,
middle=median, upper=upper.hinge, ymax=upper.whisker), stat =
"identity")

(where lower.whisker etc are the variables from your precomputed data set)

and then add on the outliers with geom_point
