Impaired boxplot functionality - mean instead of median
Hello to all users and wizards. I am regulary using 'boxplot' function or its analogue - 'bwplot' from the 'lattice' library. But they are, as far as I understand, totally flawed in functionality: they miss ability to select what they would draw 'in the middle' - median, mean. What the box means - standard error, 90% or something else. What the whiskers mean -

Mass 'identify' on 2d-plot
Hello, dear R-users. I have 2-d dotplot with two variables: x, y. Dots on this dotplot are grouped in human-recogniseable areas. These areas are not round-shaped nor oval-shaped. They are free-form, but still recogniseable by an operator. What is ability in R to graphically (per mouse) define some area and to select all the cases felt in it? 'identify' is OK for 5-10 cases, but what

R-help Digest, Vol 36, Issue 21

As I suppose, the best way is a tree. With an orbitrary function at the ends (leaves), or at least with means of my data at the ends. What is the way to do it? As I found, ctree offers binary classification, but
