今天的推文学习一下推文中的Figure 3的簇状柱形图，没有找到论文中的作图代码，但是找到了原始数据集，有了原始数据集就可以自己写代码来做这个图

部分示例数据集

加载需要用到的R包

library(readxl)
library(ggplot2)
library(tidyverse)
library(patchwork)

Figure 3a

dat01<-read_excel("data/20220630/41586_2022_4664_MOESM4_ESM.xlsx",
                  sheet = "Fig 3a")

head(dat01)
dim(dat01)



dat01$Threat<-factor(dat01$Threat,
                     levels = dat01$Threat %>% unique())

ggplot(data=dat01,aes(x=Threat,y=n,fill=className))+
  geom_bar(stat="identity",position = "dodge")+
  theme_classic()+
  geom_vline(xintercept = 5.5,lty="dashed")+
  geom_vline(xintercept = 9.5,lty="dashed")+

        axis.text.x = element_text(angle=60,hjust = 1,vjust = 1),

  scale_fill_manual(values = c("#936eaa","#401f51",
                               "#5f6798","#de6eaa"))+
  scale_y_continuous(labels = function(x){x*100}) -> p1

Figure 3b

和Figure 3a是一样的，唯一的区别是配色不一样

dat02<-read_excel("data/20220630/41586_2022_4664_MOESM4_ESM.xlsx",
                  sheet = "Fig 3b")

head(dat02)
dim(dat02)

dat02$Threat<-factor(dat02$Threat,
                     levels = dat02$Threat %>% unique())

ggplot(data=dat02,aes(x=Threat,y=n,fill=className))+
  geom_bar(stat="identity",position = "dodge")+
  theme_classic()+
  geom_vline(xintercept = 5.5,lty="dashed")+
  geom_vline(xintercept = 9.5,lty="dashed")+
  annotate(geom = "text",x=2.5,y=0.9,label="Habitat destruction")+
  annotate(geom = "text",x=7.5,y=0.9,label="Habitat change")+
  annotate(geom = "text",x=11,y=0.9,label="Other")+
  theme(legend.position = "bottom",
        axis.text.x = element_text(angle=60,hjust = 1,vjust = 1),
        legend.title = element_blank())+
  labs(x=NULL,y="Species threatened (%)")+
  scale_fill_manual(values = c("#4868af","#e41f24",
                               "#edb91d","#973692"))+
  scale_y_continuous(labels = function(x){x*100}) -> p2

最后是拼图

p1/p2 + plot_annotation(tag_levels = "a")

论文中的figure4也是簇状柱形图，感兴趣的可以自己试着复现一下

示例数据和代码可以自己到论文中获取，或者给本篇推文点赞，点击在看，然后留言获取
