Categorical treemap in R does not show all the categories about treemap HOT 4 CLOSED

I only see three categories of ShipMode:

> table(Sample_Superstore$ShipMode)
Delivery Truck    Express Air    Regular Air 
          1146            983           6270 

Notice that Tableau not only aggregates the tiles by SubCategory, but also by ShipMode itself (as main category). Without doing this, each subcategory is assigned to one (arbitrarily chosen) category.

This should work:

treemap(grouped,
        index=c("ShipMode", "SubCategory"),
        vSize="Total_Sales",
        vColor="ShipMode",
        type="categorical"
)

I'll have to fix the data.table warning though

from treemap.

Thanks for the prompt reply. I actually put a wrong link for the data.

This is the correct link and the "Ship Mode" has four categories: 'Second Class' 'Standard Class' 'First Class' 'Same Day'. However, the treemap shows only 'First Class' .

from treemap.

My code also works for this one:

You can use fontsize.labels to omit the labels of ShipMode in the treemap itself.

Thank you! Is it possible to use a color palette in each category? I want the bigger rectangles to be deeper color. I mean one color palette in each category. I have data that has "failed" and "warning" categories and I want to use different color palettes for each one of them. I am looking for something like this:
