Exporting data to CSV format is a common and practical way to share and archive your work. CSV (Comma-Separated Values) files are widely supported by spreadsheet applications and databases, making them ideal for transferring data between different programs or collaborators. When you export a data frame to CSV in R, you create a plain text file that preserves your data in a structured, tabular form.

# Export the data_export data frame to a CSV file named "my_data.csv"
write.csv(data_export, file = "my_data.csv")

The write.csv() function is R's standard tool for exporting data frames to CSV files. In the example above, the first argument, data_export, is the data frame you want to save. The file parameter specifies the name of the CSV file to create. By default, write.csv() will include row names as the first column, but you can control this and other options by providing additional arguments, such as row.names = FALSE to exclude row names or na = "" to customize how missing values are written. Using write.csv() ensures that your data is saved in a format that can be easily shared, imported, or archived for future use.
