The “read_excel” Function in R

• Package: readxl

• Purpose: To read data from an Excel (.xlsx) file into a data frame.

• General Class: Input/Output

• Required Argument(s):

• path: A character string giving the path to the Excel file to read from.

• Notable Optional Arguments:

• sheet: A character string or index specifying the sheet from which to read data.

• range: An optional range of cells to read (e.g., “A1:C100”).

• col_names: A logical value indicating whether to read column names from the first row (default is TRUE).

• Example:

• # Example usage
  # Assume an Excel file named "data.xlsx" with a sheet named "Sheet1"
  # Read the data from the specified sheet into a data frame
  df <- read_excel("data.xlsx", sheet = "Sheet1")
  
  # Print the structure of the data frame
  str(df)

• In this example, the read_excel function from the readxl package is used to read data from an Excel file named “data.xlsx” and from the sheet named “Sheet1” into a data frame (df). The resulting data frame is then printed using the str function to display its structure.
