Recipe Objective

Exploratory Data Analysis is a crucial step before building any machine learning model on a dataset. R gives us various packages and functions to explore the dataset.

This recipe focuses on calculating the number of rows in a dataset that has been just loaded

Step 1: Loading required library and dataset

# Data manipulation package library(tidyverse) ​ # reading a dataset customer_seg = read.csv('R_82_Mall_Customers.csv')

Dataset description: It is the basic data about the customers going to the supermarket mall.

Step 2: Calculating number of rows

We use the nrow() function to calculate the number of rows

nrow(customer_seg)
200
