Creating Data Files in R: Complete Guide

There are several common methods for creating data files in R language.

1. Utilize a data frame: A data frame is the most commonly used data structure in R language, where you can store data and save it as a data file. The method to create a data frame is as follows:

# 创建数据框
data <- data.frame(
  id = c(1, 2, 3, 4),
  name = c("Alice", "Bob", "Charlie", "David"),
  age = c(25, 30, 35, 40)
)

# 将数据框保存为CSV文件
write.csv(data, "data.csv", row.names = FALSE)

1. One option:
   By using the read.table() function, you can read data from an external text file into R and save it as a data file. An example code is shown below:

# 读取外部文本文件
data <- read.table("data.txt", header = TRUE)

# 将数据保存为CSV文件
write.csv(data, "data.csv", row.names = FALSE)

1. You can save data as a text file using the write.table() function. Here is an example code:

# 将数据保存为文本文件
data <- data.frame(
  id = c(1, 2, 3, 4),
  name = c("Alice", "Bob", "Charlie", "David"),
  age = c(25, 30, 35, 40)
)

write.table(data, "data.txt", sep = "\t", row.names = FALSE)

By using the methods mentioned above, it is easy to create data files in R language and perform operations for reading and saving data.
