here it is, I think (I hope) I'm getting a little closer with this, but

error using packet 1
unused argument(s) (coef =1.5, do.out=TRUE)
by reading the help for panel.bwplot at the argument "stats" it says: "the
function must accept arguments coef and do.out even if they do not use them
(a ... argument is good enough). "
I'm not sure how to couple with this...
any help for this ?
thanks
## start code
mystats <- function(x){
out <- boxplot.stats(10^x)
out$stats <- log10(out$stats)
out$conf <- log10(out$conf) ## Omit if you don't want notches
out$out <- log10(out$out)
out$coef<-1.5 #??
out$do.out<-"TRUE" #??
out ## With the boxplot statistics converted to the log10 scale
}
bwplot(conc~site, data=test,
scales=list(y=list(log=10)),
panel= function(x,y){
panel.bwplot(x,y,stats=mystats)
}
)
No example data, so no efforts at running code.
Actually there is, in the op.
?panel.bwplot
# Notice the Usage at the top of the page. The "..." is there for a reason.
# And notice that neither 'do.out' nor 'coef' are passed in the "stats" list
# The message was talking about what arguments your 'mystats' would accept, .... not what
it would return. It's another instance of your needing to understand what the
"..." formalism is doing.
?boxplot.stats
# I would be making a concerted effort to return a list with exactly the
components listed there.
And since I'm terrible at graphics I try to learn as much as possible on
R-Help. Here it goes.

#standard graphics
dev.new()

bwplot(conc~site, data=test,

panel = function(...){

With a median _line_ it would be perfect.
(Not a follow-up, it was already answered some time ago, use pch = "|"
in panel.bwplot.)
