R help - Nov 2008 - Wireframe - labels on z-axis overlap with tick marks

Hello,

I'm trying to get the z-axis labels in the right place - they overlap 
with the tick marks and axis. How can I move them them to the left?

wireframe(volcano,zlab="",scales = 
list(arrows=F,z=list(labels=c(1:100)/1000)))

Thanks,
Andrzej
