用于添加p值的分組ggplot-有解無憂

我正在嘗試在每個分組條形圖的頂部列印 bonferroni p 值。

我正在使用的代碼是：

stat1 <- stack[1:170,] %>%
rstatix::group_by(modules) %>%
rstatix::t_test(values ~ phenotypes) %>%
rstatix::adjust_pvalue(p.col = "p", method = "bonferroni") %>%
rstatix::add_significance(p.col = "p.adj") %>%
rstatix::add_xy_position(x = "values", dodge = 0.8)
p1 <- ggplot(stack[1:170], aes(x = factor(phenotypes), y = values))  
geom_boxplot(aes(fill = modules))  
theme_prism()
# remember colour and step.group.by are referring to a column name in df_p_val
p1   stat_pvalue_manual(stat1, label = "p = {p.adj}")

它可以很好地生成 p1，但是當我想列印 p 值并顯示其重要性時，它會給出相同的警告訊息：

Warning message:
Removed 6 rows containing non-finite values (stat_bracket).

資料集是：

stack[1:170,]<- structure(list(phenotypes = c("Proneural", "Mesenchymal", "Classical",

建議將受到歡迎。我想使用, ,符號列印 p 值和重要性。

uj5u.com熱心網友回復：

您需要指定x = 'phenotypes'inadd_xy_position而不是x = 'values'：

stat1 <- stack[1:170,] %>%
  rstatix::group_by(modules) %>%
  rstatix::t_test(values ~ phenotypes) %>%
  rstatix::adjust_pvalue(p.col = "p", method = "bonferroni") %>%
  rstatix::add_significance(p.col = "p.adj") %>%
  rstatix::add_xy_position(x = "phenotypes", dodge = 0.8)

p1 <- ggplot(stack[1:170,], aes(x = factor(phenotypes), y = values))  
  geom_boxplot(aes(fill = modules))  
  theme_prism()

p1   ggpubr::stat_pvalue_manual(data = stat1, label = "p = {p.adj}")

編輯

如果你想用星星代替 p 值，你可以這樣做：

p1   ggpubr::stat_pvalue_manual(
  data = stat1 %>% 
           mutate(star = ifelse(p.adj < 0.05,
                                ifelse(p.adj < 0.001, '**', "*"), "")), 
      label = "star", hide.ns = TRUE)
