Description Usage Arguments Details Value Author(s) See Also Examples

Calculates absolute and relative frequencies of a vector x. Continuous (numeric) variables
will be cut using the same logic as used by the function `hist`

.
Categorical variables will be aggregated by `table`

. The result will contain single and cumulative frequencies for both, absolute values and percentages.

`x` |
the variable to be described, can be any atomic type. |

`breaks` |
either a numeric vector of two or more cut points or a single number (greater than or equal to 2)
giving the number of intervals into which x is to be cut. Default taken from the function |

`include.lowest` |
logical, indicating if an x[i] equal to the lowest (or highest, for |

`ord` |
how should the result be ordered? Default is |

`useNA` |
one out of |

`digits` |
integer, determining the number of digits used to format the relative frequencies. |

`...` |
further arguments are passed to the function |

If `breaks`

is specified as a single number, the range of the data is divided into breaks pieces of equal length,
and then the outer limits are moved away by 0.1% of the range to ensure that the extreme values both fall
within the break intervals.
(If `x`

is a constant vector, equal-length intervals are created that cover the single value.)

an object of type `"Freq"`

, which is basically a data.frame with 5 columns (earning a specific print routine), containing the following components:

`level` |
factor. The levels of the grouping variable. |

`freq` |
integer. The absolute frequencies. |

`perc` |
numeric. The relative frequencies (percent). |

`cumfreq` |
integer. The cumulative sum of the absolute frequencies. |

`cumperc` |
numeric. The cumulative sum of the relative frequencies. |
