In class we talked about a second system to classifying verbs $($functions$)$ based upon how they impact the data used as the input. In this system, we need to think about each verb's effect along three dimensions: cases, values, and purpose.

Match each classification term with the appropriate definition.

Classification Definition

An action$/$function where the object$/$living being of the output data frame is different from that of the input data frame.

$-$

An action$/$function that results in adding more data through new cases and$/$or attributes.

$-$

An action$/$function that tells us information about a data frame.

$-$

An action$/$function where the object$/$living being of the output data frame is the same as that of the input data frame.

$-$

An action$/$function where the contents of input cells change for the output.

$-$

An action$/$function that either creates new or replaces existing columns based on existing columns in the data frame.

$-$

An action$/$function the contents of cells do not change between the input and output.

$-$

An action$/$function that alters the structural information of the data frame.

$-$

An action$/$function where the output contains new cell contents.

$-$

An action$/$function that supports carrying out another action$/$function$.$

$-$

An action$/$function that keeps the underlying structure but returns a smaller portion of the input data frame.

$-$

An action$/$function that changes the structure while preserving values.
