How to read txt data files in R language?

In R language, the read.table() function can be used to read a txt data file.

Here are the basic steps for reading a txt data file:

1. Use the setwd() function to set the working directory, making the folder where the file is located the current working directory. For example, setwd(“C:/data”).
2. Use the read.table() function to read a txt file, specify the file path and name, and assign the result to a variable. For example: data <- read.table("data.txt").
3. You can use the head() function to view the first few rows of the data you have read. For example: head(data).

Please ensure the correct spelling of the file path and name when reading a txt file, make sure the file is located in the current working directory or specified path. Additionally, the read.table() function has various parameters that can be used to control the way files are read, such as specifying delimiter and whether to include headers.
