Attempts to find the best explanatory set of variables to explain a single variable in a data set. Iterates between adding the next best variable to the set and removing the variable (if any) whose exclusion maximizes the overall score.

fbvs(dataSet,one,maxv,linear)
``` |

`dataSet` |
the n x m data frame representing n observations of m variables. |

`one` |
a string specifying the name of one variable in the dataset, for which the best explanatory set is required. Defaults to the name of the last variable in the dataset. |

`maxv` |
an integer limiting the maximum number of variables in the explanatory set. Defaults to m-1. |

`linear` |
a boolean flag which causes fbvs to use a linear model to estimate R^2
instead of matie to estimate A when running the selection algorithm.
Defaults to |

Variable names are only added to the explanatory set if their inclusion results in an increase in the association measure.

Returns a list containing the following items:

`one` |
the name of the one variable that requires the explanatory set |

`best` |
the best set of explanatory variables |

`Rsq` |
an estimate for R^2 provided by the best set of explanatory variables |

The data set can be of any dimension
