ggpubr::stat_pvalue_manual() fails when fill aesthetic is provided

[jbengler]

Hi @kassambara

ggpubr and rstatix are great packages! I truly admire your dedication and skill in creating such valuable tools for the community!

Expected behavior

The plot should be rendered regardless whether aes(fill) is provided or not.

Actual behavior

Error:
! Problem while computing aesthetics.
ℹ Error occurred in the 2nd layer.
Caused by error:
! object 'supp' not found
Run `rlang::last_trace()` to see where the error occurred.

Steps to reproduce the problem

library(ggpubr)
library(rstatix)

df <- ToothGrowth
df$dose <- as.factor(df$dose)

stat.test <- df %>%
  group_by(dose) %>%
  t_test(len ~ supp) %>%
  add_xy_position(x = "dose")

# this works
ggplot(df, aes(x = dose, y = len, color = supp)) +
  geom_boxplot() +
  stat_pvalue_manual(stat.test)

# this fails
ggplot(df, aes(x = dose, y = len, color = supp, fill = supp)) +
  geom_boxplot() +
  stat_pvalue_manual(stat.test)

# this also fails
ggplot(df, aes(x = dose, y = len, fill = supp)) +
  geom_boxplot() +
  stat_pvalue_manual(stat.test)
