跟着Nature学作图：R语言ggplot2频率分布直方图和散点

论文

A saturated map of common genetic variants associated with human height

代码没有公开，但是作图数据基本都公开了，争取把每个图都重复一遍

今天的推文重复论文中的extended Figure4 频率分布直方图和散点图添加误差线

首先是图a频率分布直方图

library(readxl)
dat<-read_excel("extendFig4.xlsx",
                sheet = "Panel a")
dat

colnames(dat)<-"Var1"
library(ggplot2)
library(ggh4x)


ggplot(data=dat,aes(x=Var1))+
  geom_histogram(bins = 25,
                 color="white",
                 fill="#aadbe9")+
  scale_x_continuous(limits = c(0.5,3),
                     breaks = seq(0.5,3,by=0.5))+
  scale_y_continuous(limits = c(0,300),
                     breaks = seq(0,300,50))+
  geom_vline(xintercept = 0.75,lty="dashed",color="#aadbe9")+
  geom_vline(xintercept = 2.25,lty="dashed",color="#aadbe9")+
  geom_segment(aes(x=2.5,xend=2.5,y=50,yend=0),
               arrow = arrow(),
               color="red")+
  annotate(geom = "text",x=2.5,y=50,label="Observed",
           vjust=-1)+
  geom_segment(aes(x=0.75,xend=2.25,y=250,yend=250),
               arrow = arrow(ends = "both",
                             angle=20,
                             length = unit(3,'mm')),
               color="#aadbe9")+
  annotate(geom = "text",x=1.5,y=250,
           label="Null distribution (1,000 draws)",
           vjust=-1)+
  theme_classic()+
  guides(x=guide_axis_truncated(trunc_lower = 0.5,
                                trunc_upper = 3),
         y=guide_axis_truncated(trunc_lower = 0,
                                trunc_upper = 300))+
  labs(y="Frequency",
       x="Enrichment folde of OMIM genes\nnear GWS SNPs with a density > 1")

第二个图b

datb<-read_excel("extendFig4.xlsx",
                sheet = "Panel b")
datb
ggplot(data=datb,aes(x=`Minimum Signal Density`,
                     y=`Enrichment statistic`))+
  geom_point()+
  geom_errorbar(aes(ymin=`Enrichment statistic`-`Standard Error of Enrichment Statistic`,
                    ymax=`Enrichment statistic`+`Standard Error of Enrichment Statistic`),
                width=0.4)+
  scale_x_continuous(limits = c(0.5,10.5),
                     breaks = 1:10)+
  scale_y_continuous(limits = c(0,9),
                     breaks = 0:8)+
  theme_classic()+
  guides(x=guide_axis_truncated(trunc_lower = 1,
                                trunc_upper = 10),
         y=guide_axis_truncated(trunc_lower = 0,
                                trunc_upper = 8))+
  labs(x="Minimum Signal Density",
       y="Enrichment-fold of OMIM genes\nnear GWS SNPs")

最后是拼图

library(patchwork)
p1+p2
