更改条形图图例的位置

Question

我的传说与我的条形图重叠 - （stackoverflow不允许我发布图片）

我搜索了一些类似的问题但未能解决我的问题。我可以补充一点，我是R的新手。如果有人能提供帮助，我将非常感激。

这是我的剧本

mids<-barplot(mean.growth,beside=T,legend=T, ylim=c(0,0.01), ylab="Growth (mm)")
arrows(mids,mean.growth-se.growth,mids,mean.growth+se.growth,length=0.1, code=3, angle=90)

text(mids,mean.growth+0.003,labels=c("bc","a","b","cd","bc","bcd","cd","d","cd","d","d","cd"))

Answer 1

如果您阅读?barplot，您会看到您可以提供要传递给'legend（）'的参数列表。明显的建议是设置x参数，如：

barplot(mean.growth,
        beside=T,
        legend=T, 
        args.legend = list(x = 'topleft') # or 'top','bottom','left','right',etc.
        ylim=c(0,0.01), 
        ylab="Growth (mm)")

或展开xlim或ylim参数以为图例腾出空间。
