Is it possible to change the overall white background color (not the value color) but the white background color to say black with the treemap package?
treemap(agg, #Your data frame object
index=c("Course", 'variable'), #A list of your categorical variables
vSize = "value", #This is your quantitative variable
type="value", #Type sets the organization and color scheme of your treemap
vColor='value',
palette = "RdYlGn", #Select your color palette from the RColorBrewer presets or make your own.
#title="Spending in President Obama's 2017 Budget", #Customize your title
fontsize.title = 14, #Change the font size of the title
title = "",
position.legend = 'bottom',
bg.labels = 0,
)
