R help - Jan 2009 - connecting boxplots

Hii,

I created some boxplots with this commands:

x <-read.table(file="test.txt")	
x$group <- rep(1:8, each=5)
boxplot(V3~gruppe, data=x) 

Now, I will connect the boxplots to each other to the min, max and median
values. 
Can anybody help me how to do it ?

greetings,
J

In other words: I will connect the median, min and the max area of the
boxplot with a line.
The function lines() could help me, but I don't know which parameters the
lines() function should have.

Or with package ggplot2 :

library(ggplot2)

c <- qplot(cyl, mpg, data=mtcars)

c + geom_boxplot(aes(group = factor(cyl))) +
  stat_summary(fun = median, geom = "line", colour = "red")
+
  stat_summary(fun = function(x) min(x), geom = "line", colour =
"blue") +
  stat_summary(fun = function(x) max(x), geom = "line", colour =
"green")
