This function creates either a violin plot, a box plot, or a mix of two for between-group or between-condition comparisons with results from statistical tests in the subtitle. The simplest function call looks like this-set.seed(123) ggbetweenstats( data = iris, x = Species, y = Sepal....

对手头的数据,你需要对每个变量按照固定分组画一个boxplot,并加上Kruskal-Wallis多组检验结果及post-hoc两两比较结果,其中两两比较的结果只需要有显著性的。以此画多个图后将他们“拼图”成一个。 以iris数据集为例,根据以下代码用ggplot2绘制了"Sepal.Width"变量的基本箱线图,并用ggpubr包的stat_compare_means...
尽管不显著,但是还是想看下数据的分布是如何的,那么这里将展示boxplot、barplot和line作图结果,以及如何添加显著性标识。 1 | boxplot p<-ggboxplot(work_df,x="variable",y="value",color="Treament",palette="jco",add="jitter")# palette可以按照期刊选择相应的配色,如"npg"等p+stat_compare_means(aes(...
