Matrix will be transformed into a long-form data frame, where each row represents a unique combination of matrix indices and their corresponding values. The resulting data frame will contain the following columns:
.row_names
and .row_index
: the row names (only applicable when names
exist) and an integer representing the row index of the original matrix.
.column_names
and .column_index
: the column names (only applicable
when names exist) and column index of the original matrix.
value
: the actual value.
A matrix-like object.
