Description

This function helps create highcharts treemaps from data frames.

Usage

hctreemap2(data, group_vars, size_var, color_var = NULL, ...)

Arguments

data	data frame containing variables to organize each level of the treemap on
group_vars	vector of strings containing column names of variables to generate treemap levels from. the first listed column will specify the top level of the treemap. the unique values in each of these columns must have no intersection (including NAs).
size_var	string name of column containing numeric data to aggregate by
color_var	string name of column containing numeric data to color by. defaults to same column as size_var
...	additional shared arguments for the data series (https://api.highcharts.com/highcharts/series).

Value

highchart plot object
