Dear R-helpers,

I would like to draw white lines in my barplots to improve the
visualization.

I include an example:

barplot(sample(1:100,15),width=0.59,horiz=T,col="steelblue",border="NA",axes=F,ylim=c(0,10),xlim=c(0,100))
  abline(v = seq(10, zehnind, by = 10), col = "white")
axis(1,at=ticks,las=1,labels=paste(ticks,"%",sep=""))

my problem is, that the white lines are not long enough at the top.

I also tried the function lines and asix, which didn't work either, neither
did changing the ylim.

Does somebody know how to do this?

Marion
