Urgentie: Hoog Dear R's (most likely Hadley), I want to build a stacked bar plot where I would like to define which colours will be used for each of the groups. However, I do not seem to find a way to do this, even if I've been looking over many places. I have tried several variations, and my final try was this code, but I still do not manage to get the colours as I pre-define. Any hints about how to get this? Thanks in advance, Pedro ============================================ my code: >plotdata1<-data.frame(x=rep(factor(1:4),4), y=rep(0.1*(1:4),4), +group=as.character(rep(c('white', 'red', 'blue', 'green'),rep(4,4)))) >plot0<-ggplot() >plot3<-plot0+layer(data=plotdata1, mapping=aes_string(x='x',y='y', +fill='group'),geom='bar', stat='identity', position='stack') >print(plot3) ______________________________________________ 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. ______________________________________________ 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.
