Question

6 multiple choice 1 point what will be the number of rows in the resulting data frame after combining two data frames using rbind()? same as the number of rows in the second data frame. same as the number of rows in the first data frame. sum of the number of rows in both data frames. depends on the column names of the data frames.

Explanation:

In R, the rbind() function is used to row - bind data frames. It stacks the rows of one data frame below the rows of another. So, the number of rows in the resulting data frame is the sum of the number of rows in both data frames. The column names must be the same (or can be made the same through appropriate handling, but the row - counting logic is based on the sum of rows).

Answer:

Sum of the number of rows in both data frames.
