R中的樹形圖Ovreall背景色

Question

是否可以通過樹形圖包更改整體白色背景顏色（而不是值顏色），但可以將白色背景顏色更改為黑色？

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, 
)

我不知道在樹形圖內是否可行，但是通過將樹形圖轉換為ggplot，我可以控制很多格式。 將樹圖轉換為ggplot
