ggboxplot箱线图上下限线条变粗如何调整

使用ggboxplot函数作图，代码如下：ggboxplot(JW1205_2, x = "Ratio", y = "Score",color = "Ratio", ylab="Score", shape="Ratio",bxp.errorbar =TRUE, bxp.errorbar.width = 0.1,size=10)+geom_jitter(size=20,aes(shape=Ratio, color=Ratio))，如图所示，上下限的线条太细了，如何变粗？

和 geom_boxplot 函数一样，用 size 参数控制

1. ggboxplot(data = ToothGrowth, x = "dose", y = "len",
   
2.           color = "dose", palette = "npg",
   
3.           add = "jitter",
   
4.           size = 1.2)
