I'm having trouble producing a barplot using the functions in ggplot2. When I use the position="dodge" option, the bars are plotted but also a number of spurious markers. More specifically, a number of black dots are plotted in the graph that should not be there. This behaviour is not seen when calling the same functions without the position="dodge".
Can someone shed some light on this? How can I avoid this?
qplot(DT$N,DT$D,fill=factor(DT$C))+ geom_bar(stat = "identity")
#in the resulting plot, a number of black markers are added that should not be there
qplot(DT$N,DT$D,fill=factor(DT$C))+ geom_bar(stat = "identity", position="dodge")
#end of example
