R: Create Empty Data Frame

In R language, you can create an empty data frame using the data.frame() function. For example, you can create an empty data frame named empty_df using the following code:

empty_df <- data.frame()

This will create an empty data frame with no rows or columns. If you need to specify the column names and data types for the data frame, you can add the corresponding parameters in the data.frame() function. For example, the following code creates an empty data frame named empty_df with two columns, A and B.

empty_df <- data.frame(A = numeric(0), B = character(0))

This creates an empty data frame with two columns, one numeric and the other character. Column names and data types can be adjusted as needed to create an empty data frame that meets specific requirements.
