How to find number of rows in a dataframe in R?
How to find number of rows in a dataframe in R?
This recipe helps you find number of rows in a dataframe in R
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
