qqnorm(plotdata$CWRES) qqline(plotdata$CWRES) 坐标轴标签设置

# 设置x轴标签
xlabel <- expression(paste("Theoretical quantiles of ", epsilon[i]))
# 设置y轴标签
ylabel <- expression(paste("CWRES of ", epsilon[i]))
# 绘制Q-Q图并添加坐标轴标签
qqnorm(plotdata$CWRES, xlab = xlabel, ylab = ylabel)
qqline(plotdata$CWRES)

可以使用scale_color_manual()函数和scale_fill_manual()函数来修改图例名和合并填充图例与颜色图例。

修改后的代码如下：

ggplot(plotdata,aes(x=RDA1,y=RDA2,color=plotdata$Group, fill=plotdata$Group))+
geom_point(size=4,aes(shape=plotdata$Treatment))+
stat_ellipse(aes(fill=plotdata$Group),geom = "polygon",linewidth=0.6,level = 0.95,alpha = 0.1)+

为了调整箭头与文本的位置，你需要修改以下两行代码：

geom_segment(data=RDAE,aes(x = 0, y = 0, xend = RDAE[,1]*3.5, yend =  RDAE[,2]*3.5),arrow = arrow(length = unit(0.03, 'npc')),linewidth =0.4,color="gray2",size = 3)+    #箭头

geom_text(data = RDAE,aes(RDA1 * 4,RDA2 * 4,label = rownames(RDAE)),color = 'gray2',size = 4)+

你可以尝试通过修改箭头和文本的坐标来调整它们的位置。比如，你可以将 `geom_segment` 中的 `xend` 和 `yend` 的值调整为 RDAE 中的值乘以一个倍数，来改变箭头的位置；将 `geom_text` 中的 `RDA1` 和 `RDA2` 的值乘以一个倍数，来改变文本的位置。具体的代码可以根据你的实际需求进行修改。
