What is the difference between Dataframe and matrix in R?
The two most important data structures in R are Matrix and Dataframe, they look the same but different in nature….Application & Usage.
| Matrix | Dataframe |
|---|---|
| The data stored in columns can be only of same data type. | The data stored must be numeric, character or factor type. |
| Matrix is homogeneous. | DataFrames is heterogeneous. |

Something not mentioned by @Michal is that not only is a matrix smaller than the equivalent data frame, using matrices can make your code far more efficient than using data frames, often considerably so.
Is data frame same as matrix?
Both represent ‘rectangular’ data types, meaning that they are used to store tabular data, with rows and columns. The main difference, as you’ll see, is that matrices can only contain a single class of data, while data frames can consist of many different classes of data.
