Hi, I want to plot 2 variables (confidence intervals) in a single xyplot. I have a dataframe with variables Yup, Ylo, X and Z and I want to have a xyplot with both variables ploted. I'm trying with
xyplot(Yup~X|Z, panel=function(x){...})
but this way I'm not able to pass variable Ylo into the function...
How can I do this ?
Thanks
EJ
