## Class FLQuantPoint

### Description

The `FLQuantPoint` class summarizes the contents of an `FLQuant` object with multiple iterations along its sixth dimension using a number of descriptive statistics.

An object of this class has a set structure along its sixth dimension (iter), which will always be of length 5, and with dimnames mean, median, var, uppq and lowq. They refer, respectively, to the sample mean, sample median, variance, and lower (0.25) and upper (0.75) quantiles.

Objects of this class wil be typically created from an `FLQuant`. The various statistics are calculated along the iter dimension of the original `FLQuant` using `apply`.

### Slots

.Data
  The main array holding the computed statistics. `array`.
units
  Units of measurement. `character`.

### Extends

FLQuant array
