Hey Paolo,
you should specify las BEFORE you send the axis command.
It would also be good to set greater margins, this needs to be set before the
entire plot, thus in following order:
par(las = 3, mar=c(6,2,2,2))
plot(ExtAvgCWV, ann=FALSE, xaxt="n", yaxt="n" )
axis(side =1 , at = tickplaces, labels = Labels)
If you only want to use las, you can also use this as an arument in the axis
function.
HTH,
Berry
