Create Data Frame in R: Quick Guide

To create a data frame, you can use the following method:

1. Use the data.frame() function:

# 创建一个包含姓名和年龄的数据框
df <- data.frame(Name = c("Alice", "Bob", "Charlie"),
                 Age = c(25, 30, 35))

1. Using the functions data.frame() and cbind():

# 创建一个包含姓名、年龄和性别的数据框
name <- c("Alice", "Bob", "Charlie")
age <- c(25, 30, 35)
gender <- c("Female", "Male", "Male")

df <- data.frame(cbind(Name = name, Age = age, Gender = gender))

1. Read external data files using the read.table() function.

# 从外部csv文件中读取数据创建数据框
df <- read.table("data.csv", header = TRUE, sep = ",")

No matter what method you use, the created data frame can be viewed using the print() function.
