今天遇到一个图，需要有R绘制一个展示平均数，误差的的点图，并进行数据统计，如下图所示

数据格式如下

data

library(ggplot2)
p=ggplot(data,aes(x = group,y = mean,color = group))+
  xlab('')+ylab('Percent %')+
  facet_wrap(~metacluster,scales = 'free')+
  geom_errorbar(aes(ymin=mean-sd, ymax=mean+sd),
                width=.2,position=position_dodge(.9))+
  geom_point(aes(x = group,y = mean,shape=group))+
  theme(panel.grid.major =element_blank(), 
        panel.grid.minor = element_blank(), 
        panel.background = element_rect(fill = 'transparent',colour ='gray'),
        panel.border=element_rect(fill=NA,colour='black'),
        plot.background = element_rect(fill = 'transparent',colour ='gray'),
        legend.position = 'top')

#加显著性

data_p

data_p1=data_p[which(data_p$lab=='*'),]

#geom_text添加显著性的*
#加横线
geom_segment
p1=p+geom_text(aes(label = lab),
               nudge_x=-0.5,
               nudge_y=24,color ="black")+
  geom_segment(aes(x = 1 ,xend = 2,
                   y = 24,yend = 24),
               data=data_p1,
               color ='black')
