# Create a bar plot with error bars (mean +/- sd) bp2 <- ggbarplot( df, x = "dose", y = "len", add = "mean_sd", color = "supp", palette = c("#00AFBB", "#E7B800"), position = position_stack() ) # Add p-values onto the bar plots # Specify the p-value...
logical. IfTRUE, flip x and y coordinates so that horizontal becomes vertical, and vertical, horizontal. When adding the p-values to a horizontal ggplot (generated usingcoord_flip()), you need to specify the optioncoord.flip = TRUE.
library(ggpubr) library(rstatix) # Transform `dose` into factor variable df <- ToothGrowth df$dose <- as.factor(df$dose) head(df, 3) # Create a bar plot with error bars (mean +/- sd) bp2 <- ggbarplot( df, x = "dose", y = "len", add = "mean_sd", color = "supp",...
