Dear List, (self-contained example + version info at the bottom)
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? #self-contained example: library(ggplot2) D<-runif(30) N<-rep(c(1:10),3) C<-rep(c(1:3),10) DT<-data.frame(D=D,N=N,C=C) #works ok 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 version info: Windows xp 64 R version 2.11.1 (64 bit) ggplot2 version 0.8.8 ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
