R Introduction

bookdata.frame() Function

The data.frame() function creates a data frame from vectors or lists. Each vector becomes a column, and its variable name is used as the column name.

Example


              
12345678

            
# Data
name <- c("Alex", "Julia", "Finn")
age <- c(24, 43, 32)
gender <- c("M", "F", "M")

# Create a data frame
test <- data.frame(name, age, gender)
test
copy

The resulting data frame has three columns (name, age, and gender), with column names automatically taken from the variable names.

Task

Swipe to start coding

You have two vectors: items and prices, containing the names and prices of goods in a local furniture store.

Your tasks are to:

  1. Create a data frame named store with two columns, items and prices (these are the respective variable names).
  2. Output store variable value.
