rate_DF | R Documentation |

Count data frame's row rate according to several variables

rate_DF( data, rate.var, weights, return = "add", as.percent = FALSE, percent.var, digits = 2 )

`data` |
data frame with rated variables |

`rate.var` |
character; vector of data frame column names with numeric variables of range (0-1) that should be used for rating |

`weights` |
numeric; vector of variables' weights (their sum must be 1) |

`return` |
character; return object; possible values are: |

`as.percent` |
logical; if some rated variables are percentages |

`percent.var` |
character; vector of data frame column names with rated variables that are percentages |

`digits` |
integer; number of decimal places to round the rate value |

This function counts rate as `rate = var1*weight1 + var2*weight2 + var3*weight3 +...`

etc.
All variables must be in range (0-1) and sum of weights must be 1. If you use percentages as rating variable, use `as.percent = TRUE`

.
Those variables would be divided by 100 before rating and then would be multiplicated by 100 after rating.

`rate.var`

and `percent.var`

must be exact column names as in data frame.

Vector or data frame with rate values.
