Hi,
I am working on stacked bar plot and want to add marker(arrow) in stacked
bar plot.
DF=data.frame(names=c("tomato", "potato", "cabbage", "sukuma-wiki",
"terere"), freq=c(7,4,5,8,20))
barplot(as.matrix(DF[,2]), col=heat.colors(length(DF[,2])), legend=DF[,1],
xlim=c(0,9), width=2)

Image with marker:
