HI folks
I'm wanting to do box plots of just 2 of my wells.
I can do it for all of them by using
boxplot(Barium~Well.ID,data=mydata, main="Barium", ylab="mg/L")
to do for all 4 wells
Anyone have a sugestion on how to do it for only 2 wells like MW-1 and MW-2?
The data can be found?

Hi David,
Try this:
dddf<-read.csv("mydata.csv")
dddf12<-dddf[dddf$Well.ID=="MW-1" | dddf$Well.ID=="MW-2",]
dddf12$Well.ID<-factor(dddf12$Well.ID,levels=c("MW-1","MW-2"))
boxplot(Barium~Well.ID,dddf12)
Jim
