如何在R中绘制堆积条形图?

标签: r plot legend stacked

我有一个示例数据,如下所示: 看起来很简单,但我找不到出路,我是R的新手。请帮忙!

clust4   catch
    1  131711493
    2   41683530
    3  143101724
    4   35849946 

如何获取堆叠的条形图,该条形图显示每个簇的百分比 catch列的值?并获得以下图例名称:

group(legend name)
Cluster1
Cluster2
Cluster3
Cluster4

我已经尝试了很多次,但是它只显示了4种不同的堆叠条形图,并且也无法将图例名称从1,2,3,4更改为簇1,...)

很抱歉没有插入任何照片,因为我没有足够的声誉。

这是使用ggplot2库在R中堆叠条形图的基本代码 根据您的数据集更改变量并将其绘制

# library
  library(ggplot2)

# create a dataset
specie=c(rep("sorgho" , 3) , rep("poacee" , 3) , rep("banana" , 3) , 
rep("triticum" , 3) )
condition=rep(c("normal" , "stress" , "Nitrogen") , 4)
value=abs(rnorm(12 , 0 , 15))
data=data.frame(specie,condition,value)

# Grouped
ggplot(data, aes(fill=condition, y=value, x=specie)) +
geom_bar(position="dodge", stat="identity")

# Stacked
ggplot(data, aes(fill=condition, y=value, x=specie)) +
geom_bar( stat="identity")

# Stacked Percent
ggplot(data, aes(fill=condition, y=value, x=specie)) +
geom_bar( stat="identity", position="fill")

解决方案1:ggplot2

library(tidyverse)
df %>% mutate(catch = catch / sum(catch),
              clust4 = paste0("Cluster-", clust4)) %>%
  ggplot(aes(x = "", y = catch, fill = clust4)) +
  geom_bar(stat = "identity", color = "black") +
  coord_flip()

enter image description here


解决方案2:图形

prop <- df$catch / sum(df$catch)
color <- RColorBrewer::brewer.pal(4, "Set2")
barplot(as.matrix(prop), horiz = T, col = color,
        xlim = c(0, 1.2), ylim = c(-0.5, 2),
        legend.text = paste0("Cluster-", 1:4),
        args.legend = list(x = "right", bty = "n"))

     clust4     catch
