buildPareto | R Documentation |

Maps a factor to another factor in a one to many relationship following Pareto principle. For example, 80 percent of transactions can be mapped to 20 percent of customers.

buildPareto(factor1, factor2, pareto)

`factor1` |
A factor. This factor is mapped to factor2 as given in the details section. |

`factor2` |
A factor. This factor is mapped to factor1 as given in the details section. |

`pareto` |
This defines the percentage allocation and is a numeric data type. This argument takes the form of c(x,y) where x and y are numeric and their sum is 100. If we set Pareto to c(80,20), it then allocates 80 percent of factor1 to 20 percent of factor 2. This is based on a well-known concept of the Pareto principle. |

This function is used to map one factor to another based on the Pareto argument supplied. If factor1 is a factor of customer identifiers, factor2 is a factor of transactions and Pareto is set to c(80,20), then 80 percent of customer identifiers will be mapped to 20 percent of transactions and vice versa.

A data frame with factor 1 and factor 2 as columns. Based on the Pareto arguments passed, column factor 1 is mapped to factor 2.
