我有以下數據框稱爲df
。我的問題與y軸上的訂單有關。我希望y軸上的名稱根據變量depth
排序。ggplot2,訂購y軸
如果我這樣做:
ggplot(df,aes(x=factor(name),y=depth)) + geom_bar(stat='identity') + coord_flip() + labs(y='depth',x='species')
我graph1
下方未訂購。因此,我跟着指示找到here,我根據深度命令我的因素name
水平:
df2=df[order(df$depth),]
df2$name=factor(df2$name,levels=df2$name)
ggplot(df2,aes(x=factor(name),y=depth)) + geom_bar(stat='identity') + coord_flip() + labs(y='depth',x='species')
我下面有Graph2
。但對我來說,下一步是根據Mut
變量對條進行不同的着色。
ggplot(df2,aes(x=factor(name),y=depth)) + geom_bar(stat='identity',data=subset(df2,df2$Mut==2),fill='red') + geom_bar(stat='identity',data=subset(df2,df2$Mut==1),fill='blue') + coord_flip() + labs(y='depth',x='species')
而且我得到了Graph3
不再訂購!
我怎麼能生產出graph3尊重顯示的順序graph2
