The “read.csv” Function in R

• Package: Base R (utils package)

• Purpose: To read a comma-separated values (CSV) file into a data frame.

• General Class: Input/Output

• Required Argument(s):

• file: A connection or a character string giving the name of the file to read from.

• Notable Optional Arguments:

• header: A logical value indicating whether the file has a header line with column names (default is TRUE).

• sep: The field separator character (default is ,).

• quote: The quoting character (default is ").

• Example:

• # Example usage
  # Assume a CSV file named "data.csv" with header
  # Read the CSV file into a data frame
  df <- read.csv("data.csv")
  
  # Print the structure of the data frame
  str(df)

• In this example, the read.csv function is used to read a CSV file named “data.csv” into a data frame (df). The resulting data frame is then printed using the str function to display its structure.
