Dear Researchers,

I wish to plot mean, standard deviation, and standard error and I am using
bwplot(). I have the following problems and sorry if maybe there are simple
questions:

1- use color black for standarddevuation line and add horizontal end bar
(as the commun graphic in scientific papers)
2- change the label in x axes (es; A and B, respect 1 and 2)
3- add the standard error around the mean with a shape of a rectangular
(high equal to standard error and length possibile to be visible in a
graphic)

this is an exmple to explain better

A <- data.frame(class=rep(1,25))
B <- data.frame(class=rep(2,25))
class <- data.frame(rbind(A,B))
mydata <- data.frame(H=runif(50),class)

bwplot(H~class, data=mydata,
horizontal=FALSE, panel=panel.meansdplot,mean.col = "black")


really thanks and good week-end

Gianni
