## Colors from the HCL spectrum

### Description

Produces colors from the HCL (Hue Chroma Luminance) spectrum, based on the number of levels from a factor.

### Usage

```
hclr(x, starth = 25, c = 50, l = 75, alpha = 1, fixup = TRUE)
```

### Arguments

`x` |
Number of factor levels, or the factor itself, or a frequency distribution from a factor |

`starth` |
Starting point for the hue (in the interval 0 - 360) |

`c` |
chroma - color purity, small values produce dark and high values produce bright colors |

`l` |
color luminance - a number between 0 and 100 |

`alpha` |
color transparency, where 0 is a completely transparent color, up to 1 |

`fixup` |
logical, corrects the RGB values foto produce a realistic color |

### Details

Any value of `h`

outside the interval 0 - 360 is constrained to this interval using
modulo values. For instance, 410 is constrained to 50 = 410

### Value

The RBG code for the corresponding HCL colors.

### Examples

```
aa <- sample(letters[1:5], 100, replace = TRUE)
hclr(aa)
# same with
hclr(5)
# or
hclr(table(aa))
```
