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. My dataset currently contains 10 rows (one row per week) with the following columns: weekno (the week over which values have been summarized), minimum, 25th and 75th percentile, median, mean, and max values. Any suggestions on how I can plot this in R to produce a box- whisker plot (one box per week of data) ? I have seen http:// finzi.psych.upenn.edu/R/library/graphics/html/bxp.html but am not sure how to shape my summarized data correctly to produce the plot. Many thanks in advance, Avram
box-whisker plot from pre-summarized data?

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 Hadley
