Can you think of a way to make adding a row to the matrix worthwhile?

There is no real need to add a new row to the matrix as it is. If we want to add new information, it would surely belong in a new column.

So, what we can do, if we really want to use the rbind() function, is to transpose the matrix, include a new row (with the new
information) and transpose it back.

This way, you will have effectively added a column, but by using the rbind() command.
