Method Definition
vDataFrame.append Merges the vDataFrame with another vDataFrame or an input relation.
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.
