rgb.tables {colorRamps} | R Documentation

## constructs color palettes with sharp breaks

### Description

`rgb.tables` wraps `table.ramp` and simply passes values supplied in the `red`, `green` and `blue` arguments. `table.ramp` makes a color ramp with a flat top.

### Usage

    rgb.tables(n, red = c(0.75, 0.25, 1), green = c(0.5, 0.25, 1), blue =
    c(0.25, 0.25, 1))
    table.ramp(n, mid = 0.5, sill = 0.5, base = 1, height = 1)

### Arguments

`n` | number of colors to generate
`red` | a length 3 vector with values `mid`, `sill` and `base`
`green` | same as `red`
`blue` | same as `red`
`mid` | table center on (0, 1)
`sill` | width of table top on (0, 1)
`base` | width of table base on (0, 1)
`height` | sill height on (0, 1)

### Value

`rgb.tables` returns a color palette. `table.ramp` returns a simple vector of values.
