Adding Header to a CSV file in R using write.csv() Function

To add headers to the columns of a CSV file in R, we will use write.csv() function. Let us first understand its syntax.

Syntax:
write.csv(data, path, row.names, col.names)

Parameters:

• data: the data set to be added to the CSV file
• path: the path where the file is to be created
• row.names: name of the rows in a CSV file. When set to FALSE, the CSV file won’t have a row name
• col.names: name of the columns in a CSV file. We can specify our own column names to the columns.

In R programming, the write.csv() function is used to save data frames as comma-separated values (CSV) files. When a CSV file is created using the write.csv() function, it does not contain a header by default. However, it is often useful to include a header row in the CSV file that contains the names of the variables in the data frame.
