Background

Bokeh is a visualization library that provids a flexible and powerful declarative framwork for creating web-based plots. Bokeh renders plots using HTML canvas and provides many mechanism for interactively

Installation

The rbokeh package can be installed from CRAN:

library(rbokeh)

## Warning: package 'rbokeh' was built under R version 3.6.3

## Registered S3 method overwritten by 'pryr':
##   method      from

Plots are constructed by intializing a figure() and then adding layers on top through various glyphs available in Bokeh

Before providing a tutorial, we first show several examples of plots created with rbokeh. This will both give a feel for what the syntax looks like and provide some motivation to go through the more procedural tutorial. We thought this would be a more enjoyable way to begin than looking at 50 different versions of a plot of the iris data with different parameter settings

Speaking of the iris data, outt first plot:

p<- figure()%>% ly_points(Sepal.Length,Sepal.Width,data=iris,color=Species,glyph = Species,hover=list(Sepal.Length,Sepal.Width))

Here since we are specifying color and glyph by Species, a legend is automatically created and the points are colored accoding to the default color scheme. You can hover over points to see the tooltips we added with the hover argument. You can also play around with the other interactive components such as panning and zooming

We can also specify legend entries manually

z<- lm(dist~speed,data=cars)

p<- figure(width=600,height=600)%>% ly_points(cars,hover=cars)%>%ly_lines(lowess(cars),legend="lowess")%>%ly_abline(z,type=2,legend="lm")
