Hi all,
I am making 2 barplots with 3 different bars inside with command :
 
bar.wdHo<-barplot(wdHo.mean, names=c(""), cex.lab=1.0, cex.axis=1, cex.names=1, ylim=c(0,15), xlab="", ylab=expression(paste("Thickness (mm"^{2},")")), density=c(0,27,200), col=c("grey90","black","grey"), beside=TRUE, axis.lty=1)

and the other one : 
bar.wdHo<-barplot(wdHo.mean, names=c(""), cex.lab=1.0, cex.axis=1, cex.names=1, ylim=c(0,5), xlab="", ylab=expression(paste("Thickness (mm"^{2},")")), density=c(0,27,200), col=c("grey90","black","grey"), beside=TRUE, axis.lty=1)

My question is :
 
how can i adjust the y range from 0,5,10 and 15? for the first barplot and the second to be 0, 2.5 and 5 ?
because, even though i put the lim=c(0,15) for the first one, but then it came out as 0,2,4,and so on (with even numbers) and the max is only 14. 
 
because also I would like to show "comparisons" of magnitudes with the other baplots /data that I have, one with max 15 and the other with maximum 5)
 
Any help/comments/suggestions are highly appreciated,
THanks in advance,
cheers,
Yakamu
