ANOVA and MANOVA tests are used when comparing the means of more than two groups (e.g., the average heights of children, teenagers, and adults). The stat_compare_means function in R is actually a specified function based on the more general compare_means tool that compares all means in a specified string, with the stat extension more specifically telling the program to take calculated p-values and significance data and assign it to the axis in ggplot graphs. FALSE never includes, and TRUE always includes. column containing the coordinates (in data units) to be used what is the convention ggpubr uses? data as specified in the call to ggplot(). For some reason, stat_compare_means () only prints the all the p-values without a bracket. Why did OpenSSH create its own key format, and not use PKCS#8? Wheelan, C.
