I have a matrix containing means and CIs (lower and upper in two columns, so three columns for every data point) for several points. I have to build a graph of these means accompained by the CIs (as wiskers). No problems with making the graph of means, but I don't know how to introduce CIs. Can anybody advise? -- View this message in context: http://www.nabble.com/CI-wiskers-tp24646309p24646309.html Sent from the R help mailing list archive at Nabble.com.

Hi, I'm having trouble using dates (created using library(chron)) as groupings for a boxplot. I have 10 repeat measurements of a variable within an individual day. The measurements were done over 10 days. I would like to plot the measurements as a box and wisker plot (using boxplot or something similar) where the days (as chron object) would be the grouping and the repeated measurements of the variable make up the box and wisker plot. I would like the spacing of the individual boxplots to reflect the time between measurements: Example using random num...

For boxplot(), is it possible to pass in a parameter to change the default way that the 1st and 3rd quartiles are computed? (specifically, I'd like to use type 6 described in the quantile function). Also, what are the options for how outliers are computed, and how can one change them? Thank you [[alternative HTML version deleted]]
