[R] Suppressing tick labels?

I am trying to suppress the tick labels on the x-axis of the

following:

barchart(richness[Wood=="V"]~Sample[Wood=="V"])

Use the scales= argument.  E.g.

  d<-data.frame(richness=log(1:12), Wood=rep(c("S","V"),each=6),
Sample=rep(1:6,2))
  barchart(richness[Wood=="V"]~Sample[Wood=="V"], data=d,
scales=list(x=list(at=numeric(0), lab=character(0))))

You can get the tick positions and labels of your choice with scales:

  barchart(richness[Wood=="V"]~Sample[Wood=="V"], data=d,
scales=list(x=list(at=c(2,5), lab=c("Two","Five"))))
