ggplot:根据条形中某个级别的%组件更改堆积条形的顺序

我已经在ggplot中创建了一个堆积条形图。

antr1$Traits4<-factor(antr1$Traits4,
                      levels=c("Flight", "Avoidance", "Investigative",
                               "Defensive aggression","Active aggression"))

ggplot(antr1, aes(Receiver3, fill=Traits4)) + 
  geom_bar(position="fill") + 
  coord_flip() +
  scale_y_continuous("", formatter="percent") + 
  scale_fill_manual(values=c("Flight"="yellow",
                             "Avoidance"="green",
                             "Investigative"="blue",
                             "Defensive aggression"="orange",
                             "Active aggression"="red"))  

很好用。但是,此时根据“Receiver3”的名称按字母顺序排列条形。我想根据“主动攻击”等级的百分比重新排序堆积的栏。

提前感谢你

如果你知道你想要的Receiver3级别的顺序,你可以通过以下方式指定:

antr1$Receiver3 <- factor(antr1$Receiver3,
                    levels=c(...list the levels in the order you'd like...),
                    ordered=TRUE)

如果Receiver3有多个级别,那么手动确定正确的顺序是令人望而却步的,你可以尝试这样的事情:

temp <- aggregate(antr1$Traits4,by=list(receiver=antr1$Receiver3),
          FUN=function(xx){
                return(sum(xx=='Active aggression')/length(xx))
          }
antr1$Receiver3 <- factor(antr1$Receiver3,levels=temp$receiver[order(temp$x)],
                     ordered=TRUE)

如果您想要相反的顺序,请将订单(temp $ x)更改为订单(temp $ x,减去= TRUE)。
