Hi, Thank you for your answer, I thought we could used something like the "axis" function ( axis(side=3,...)) in ggplot2. I didn't find something like this in ggplot and I'm a bite surprised this doesn't exist. Sometimes we need to use lattice, grid -thank you Duncan for your help, or ggplot or other package, depending on what we want to show and the type of plot. Anyway, as I really need to use the ggplot package, I suppose that I'll plot my data without the axis on the top.Have a nice day,
