Hi Julia,
I had to do a tweak on the spread.labels function (attached). Try this:

library(plotrix)
source("spread.labels.R")
plot(0:100,axes=FALSE,type="n",xlab="",ylab="")
axis(1,pos=0)
spread.labels(c(5,20,50,60,70,90),rep(0,6),ony=FALSE,
  labels=c("Bottom1","Top1","Bottom2","Top2","Bottom3","Top3"),
  offsets=rep(20,6))
