The goal of ggvega is to translate a ggplot2 object to a Vega-Lite specification.

library(ggvega)
#> Welcome to ggvega; this package is not yet fully functional, and is under active development.
library(ggplot2)

p <-
ggplot(iris) +
geom_point(aes(x = Petal.Width, y = Petal.Length, colour = Species))

as_vegaspec(p)

### Important Note

This package is in an extremely experimental state, under very active development.

At present, we can translate:

• geom_point()
• aesthetics: x, y, colour
• unit-plots; no facetting.

We have plans to expand this capability; presently, we are working out a system to add new capabilities quickly and reliably.

## Installation

You can install the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("vegawidget/ggvega")
