Get an overview of the core Tidyverse packages and their integrated approach to data science.
Introduction to Tidyverse is a free R Academy lesson on CoddyKit — lesson 1 of 3. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the R Academy learning path, one of 3 lessons in the course, and your progress syncs across the web and the CoddyKit app.
1
Introduction to Tidyverse
The Tidyverse is a collection of R packages designed for data science, making data manipulation and visualization easier.
2
Installing and Loading Tidyverse
Before using Tidyverse, install and load the package.
install.packages('tidyverse')
library(tidyverse)3
Key Packages in Tidyverse
The Tidyverse includes several useful packages:
dplyr- Data manipulationggplot2- Data visualizationtidyr- Data tidyingreadr- Importing data
4
Using dplyr for Data Manipulation
The dplyr package helps with filtering, summarizing, and transforming data.
library(dplyr)
data <- mtcars %>% filter(mpg > 20)5
Using ggplot2 for Visualization
The ggplot2 package is used for creating elegant visualizations.
library(ggplot2)
ggplot(mtcars, aes(x=mpg, y=hp)) + geom_point()6
Using tidyr for Data Tidying
The tidyr package is useful for reshaping and cleaning data.
library(tidyr)
data_long <- pivot_longer(mtcars, cols=c('mpg', 'hp'), names_to='variable', values_to='value')7
Using readr for Importing Data
The readr package is used to read data efficiently.
library(readr)
data <- read_csv('data.csv')8
9
Combining Tidyverse Functions
You can chain multiple functions together for efficient analysis.
mtcars %>% filter(mpg > 20) %>% select(mpg, hp) %>% arrange(desc(hp))10
