Hello: I would like to run a Cox proportional hazards regression on crayfish dislodgement at different water velocities by crayfish size class and substrate (rock) type. Additionally, there is a covariate variable, rock movement that may be influencing crayfish dislodgment. So... I have crayfish size class (CFSZCL) and substrate type (SUBSZ) as fixed factors influencin...

I have a plotted a stacked panel graph (single x axis and multiple y axis) using the package zoo and would like to add a title for each separate panel. I am using the script: z <- with(mydata,zoo(cbind(mydata$Water.level,mydata$Submerged.plants, mydata$Crayfish.CPUE,mydata$Carp.CPUE),Year)) plot(z,type="b",pch=16,lty=2,xlab="Year",ylab=c("Metres","Realtive density", "CPUE","CPUE"),main="") Any help would be much appreciated.
