In this recipe, we demonstrate how to use The Grammar of Graphics to construct our very first ggplot2
chart with the superstore sales dataset.
First, download the superstore_sales.csv
dataset from the https://github.com/ywchiu/rcookbook/raw/master/chapter7/superstore_sales.csv GitHub link.
Next, you can use the following code to download the CSV file to your working directory:
> download.file('https://github.com/ywchiu/rcookbook/raw/master/chapter7/superstore_sales.csv', 'superstore_sales.csv')
You will also need to load the dplyr
package to manipulate the superstore_sales
dataset.
Please perform the following steps to create a basic chart with ggplot2
:
First, install and load the
ggplot2
package:> install.packages("ggplot2") > library(ggplot2)
Import
superstore_sales.csv
into an R session:> superstore <-read.csv('superstore_sales.csv', header=TRUE) > superstore$Order.Date <- as.Date(superstore$Order.Date) >...
