plotjs

GitHub Workflow Status

The goal of plotjs is provide to a base ‘graphics’-like interface to the Chart.js JavaScript charting library. The main plotjs() function is an S3 generic like the base plot() function with methods for various base R objects.

Besides htmlwidgets, it has minimal R dependencies. Tidyverse not required!

Installation

You can install the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("arkraieski/plotjs")

Example

Here’s some example code for a basic scatter plot using R’s airquality dataset:

library(plotjs)
air <- airquality
plotjs(air$Ozone, air$Solar.R, 
       main = "New York Air Quality Measurements", 
       xlab = "Ozone (ppb)",
       ylab = "Solar Radiation (lang)",
       col = "red")

Methods

To see a list of S3 methods:

library(plotjs)
methods(plotjs)
#> [1] plotjs.default*  plotjs.density*  plotjs.factor*   plotjs.function*
#> [5] plotjs.lm*      
#> see '?methods' for accessing help and source code

More are on the way! The goal is to replicate the behavior of base R plot() methods as closely as possible while also getting the benefits of using a Chart.js-backed interactive widget. Each method has its own help page that can be accessed for additional information.

Testing

The package is tested on Windows, Linux, and MacOS.
