lattice multiple y-scale possible?

Hi:

bwplot(dat~site|parameter,data=mydat,
      layout=c(1,5),
      cex=2,
      xlab="Site Name",
      ylab="",
      labels=levels(mydat$site),
      scales=list(tick.number=list(4), rot = c(0, 90),
                  y = list(relation = 'free')))

Does that work?

Hi
I am attempting to use the lattice bwplot function to generate boxplots of
numerous parameters (1-panel/parameter) by site (x-axis). The parameters
have quite different ranges of values, so it would be best to have a
separate y-axis range for each panel. Below is a basic example of what I am
trying to do. As is seen, the y-axes need to be scaled individually to make
this useful. Any information on how to do this would be much appreciated:

rm(mydat)
rm(tempdf)

for (i in 1:5){
for (ii in 1:5){
dat<- sample(1:20)*10^ii
tempdf<- data.frame(dat)
tempdf$parameter<- paste("parameter ",ii,sep="")
tempdf$site<- paste("site",i,sep="")
if(!exists("mydat")) {mydat<- tempdf
  }else {mydat<- rbind(mydat,tempdf)}
  }
}

bwplot(dat~site|parameter,data=mydat,
      layout=c(1,5),
      cex=2,
      xlab="Site Name",
      ylab="",
      labels=levels(mydat$site), scales=list(tick.number=list(4)))

thanks
