Thanks again, I like the idea of adding transparency. I will try it. For now, I resigned myself to add points to the original barplot using points as such:
plotV<-barplot(Value[,1],space=0) dev.off() par(mar=c(4,5,3,1)) barplot(Value[,1],space=0, col="grey30",axis.lty=2) points(plotV, sampledepth[,1]/(max(sampledepth[,1])/max(Value[,i])), pch=19, col="black", xpd=TRUE) #sampledepth[,1]/(max(sampledepth[,1])/max(Value[,i] is just to relativize the values of sampledepth to fit the axis of the plot Not exactly what I want but close to it. A continuous curve that represents the "top" of the barplot would be ideal to represent sample depth (n) of each class of Value. Stacking barplot will not provide what I am looking for. Thanks much for your suggestions, I will post an update if I find a way to do exactly what I want. Still, implementing the argument "inside" in the barplot function would be the way to go but I am lacking some time to acquire the skills required to implement it.
