| Method | Definition |
| vDataFrame.append | Merges the vDataFrame with another vDataFrame or an input relation. |
| vDataFrame.cdt | Returns the complete disjunctive table of the vDataFrame. |
| vDataFrame.groupby | Aggregates the vDataFrame by grouping its elements. |
| vDataFrame.join | Joins the vDataFrame with another vDataFrame or an input relation. |
| vDataFrame.narrow | Returns the narrow table of the vDataFrame using the input vcolumns. |
| vDataFrame.pivot | Returns the pivot of the vDataFrame using the input aggregation. |
| vDataFrame.polynomial_comb | Returns a vDataFrame containing the product combination of different input columns. This function is ideal for bivariate analysis. |
| vDataFrame.recommend | Recommends items based on the collaborative filtering (CF) technique. |
| vDataFrame.sort | Sorts the vDataFrame using the input vcolumns. |
