The “write.csv” Function in R

• Package: Base R (No specific package)

• Purpose: To write a data frame to a CSV file.

• General Class: Data Output

• Required Argument(s):

• x: A data frame to be written to the CSV file.

• file: The file path or connection where the CSV file should be written.

• Notable Optional Arguments:

• row.names: Logical value indicating whether the row names should be included in the output. The default is TRUE.

• Example:

• # Example usage
  # Create a sample data frame
  data <- data.frame(
  Name = c("Alice", "Bob", "Charlie"),
  Age = c(25, 30, 22),
  Score = c(95, 88, 75)
  )
  
  # Write the data frame to a CSV file. Don’t forget the “.csv”!
  write.csv(data, file = "output.csv", row.names = FALSE)

• In this example, the write.csv function from the base R package is used to write the data frame data to a CSV file named “output.csv”. The row.names argument is set to FALSE to exclude row names in the output.
