Automatically specify error bars grouping variable

[kassambara]

In the current version, when creating a grouped bar plot with fill, user needs to specify the option add.params = list(group = ) for adding error bars by group.

library(ggpubr)
df <- ToothGrowth
df$dose <- as.factor(df$dose)
ggbarplot(df, x = "supp", y = "len",
                fill = "dose",
                add = "mean_sd", add.params = list(group = "dose"),
                position = position_dodge(0.8)) 

It would be great if ggbarplot() can automatically create error bars by groups when users forget the option add.params = list(group = )
