加载R包

knitr::opts_chunk$set(message = FALSE, warning = FALSE)

library(tidyverse)
library(patchwork)
library(cols4all)
library(tidydr)

rm(list = ls())
options(stringsAsFactors = F)

# group & color
group_names <- c("A", "B", "C")
group_colors <- c("#0073C2FF", "#EFC000FF", "#CD534CFF")
group_shapes <- c(15, 16, 17)

导入数据

dat <- data.frame(
  SampleID = paste0("S_", 1:24),
  PC1 = c(0.022770707, 0.054692482, 0.039981067, 0.007793265, 7.84e-06, -0.009869502, -0.059123147,
