Descriptive statistics by group in r

How do you describe descriptive statistics in R?
R provides a wide range of functions for obtaining summary statistics.
One method of obtaining descriptive statistics is to use the sapply( ) function with a specified summary statistic.
Possible functions used in sapply include mean, sd, var, min, max, median, range, and quantile..

How to show descriptive statistics for categorical variables?
Data for two categorical variables can also be displayed in either a clustered or stacked bar chart; a clustered bar chart is great for comparing each category of one variable between the different categories of the other variable, while a stacked bar chart is better for comparing the total for each of the categories .
What is the mean by group in R?
Calculating the mean by group in an R DataFrame involves splitting the data into subsets based on a specific grouping variable and then computing the mean of a numeric variable within each subgroup..
The group_by() function in the dplyr package is a crucial tool for data manipulation in R.
It allows us to split a data frame into groups based on one or more variables, and then apply a function to each group.
When calculating descriptives for more complex designs including more than one independent variable, you can also use the Means/ Compare Means or the Descriptive Statistics/ Crosstabs command which allow you to calculate descriptive statistics of subgroups.
