R中的树形图总体背景颜色

Question

是否可以使用 treemap 包更改整体白色背景颜色（不是值颜色）但将白色背景颜色更改为黑色？

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, 
)

我不知道它是否可以在树形图中，但是通过将树形图转换为 ggplot，我能够控制很多格式。 Converting treemap to ggplot
