orb: Start a plot

In orbis: Interactive and High-Resolution Layered Graphics with Built-in World Maps

Start a plot

Description

orb() creates a plot specification: it records the data and the mapping from variables to visual channels. Layers, labels, scales and themes are added with +. Nothing is drawn until the plot is printed or saved, so a specification is cheap to build and modify.

Usage

orb(data, ...)

Arguments

data	A data frame.
...	Aesthetic mappings, given as channel = column.

Details

Mappings are given as bare column names, in the style of a formula-free grammar: orb(df, x = wt, y = mpg, colour = cyl). The recognised channels are x, y, colour (or color), fill, size, label, group and tooltip.

Value

An object of class orb_spec.

Examples

p <- orb(mtcars, x = wt, y = mpg, colour = cyl) + orb_points()
