x <- replicate(20,rnorm(50))
boxplot(x,notch=TRUE,main="Notched boxplot with error bars")
error.bars(x,add=TRUE)

## Ag
boxplotDAS(log10(Ag)~Aquifer,ylab="",xlab="Ag (mg/l)", main="",
data=samples, notch=TRUE, horizontal=TRUE, xaxt="n", col="gray85")
error.bars(samples,add=TRUE)
axis(1,at=log10(a<-sort(c((10^(-50:50))%*%t(c(1,5))))),labels=a, tick=T)
abline(v=log10(a),lty=3...
