    R functions:

    1summarise_all(): apply summary functions to every columns in the data frame.2summarise_at(): apply summary functions to specific columns selected with a character vector.3summarise_if(): apply summary functions to columns selected with a predicate function that returns TRUE..

  • How to calculate summary statistics by group in R?

    In this method to calculate the summary statistics by group, the user needs to simply call the inbuilt tapply() function with the summary argument of this function passed with the given data for which the summary statistics is to be calculated, and under this method, user will take a summary function as the third .

    How to Group Data With R

    1. Load the data set into Tibble
    2. Enter the function group_by to group the information
    3. Use summarise to analyze your data
    4. Create a new column with mutate
    5. Ungroup your data with ungroup()

  • First, we'll need to create some exemplifying data:

    1seed(549298) # Create example data data \x26lt;- data. 2summary(data$x) # Summary of entire data # Min. 3tapply(data$x, data$group, summary) # Summary by group using tapply # $A # Min. 4packages("dplyr") # Install dplyr package library("dplyr") # Load dplyr package.

Example 1: Descriptive Summary Statistics by Group Using Tapply Function

In this example, I’ll show how to use the basic installation of the R programming language to return descriptive summary statistics by group

Example 2: Descriptive Summary Statistics by Group Using dplyr Package

Another alternative for the computation of descriptive summary statistics is provided by the dplyr package. First

Example 3: Descriptive Summary Statistics by Group Using Purrr Package

In Example 3, I’ll illustrate another alternative for the calculation of summary statistics by group in R
