[R] lattice multiple y-scale possible?

[Steve Corsi]

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
Steve
