The “read_csv” Function in R

• Package: readr

• Purpose: To read a CSV file into a data frame.

• General Class: Data Import

• Required Argument(s):

• file: The path to the CSV file to read.

• Notable Optional Arguments:

• col_names: Logical. If TRUE, the first row of the CSV file is treated as the column names. The default is TRUE.

• skip: Integer. Number of lines to skip before reading data. The default is 0.

• na: Character vector specifying additional strings to interpret as missing values. The default is c(““,”NA”).

• Example (with Explanation):

• # Load necessary packages
  library(readr)
  
  # Read a CSV file into a data frame
  data <- read_csv("data.csv")
  
  # Display the structure of the data frame
  str(data)

• In this example, the read_csv function from the readr package is used to read a CSV file named “data.csv” into a data frame called data. By default, the function assumes that the first row of the CSV file contains column names. The structure of the resulting data frame is then displayed using the str function. This function is commonly used to import CSV data into R for analysis.
