R Tree-maps - make background label transparent

I am trying to create a treemap using R package treemap

. Here is the code (this is a sample from the package)

library(treemap)
data(GNI2010)
treemap(GNI2010,
        index=c("continent", "iso3"),
        vSize="population",
        vColor="GNI",
        type="value")

The problem I ran into was the color of the labels. When I only have one index, then the output is ok:

library(treemap)
    data(GNI2010)
    treemap(GNI2010,
            index=c("iso3"), #single index
            vSize="population",
            vColor="GNI",
            type="value")

enter image description here

But when I have multiple indices, the label changes color. I just want all labels to be transparent. Is it possible?

As I wrote this, I found the solution in the documentation: you just need to add the option bg.lables = 0

. Its range is from 0 to 255, the default is 220.

library(treemap)
data(GNI2010)
treemap(GNI2010,
        index=c("continent", "iso3"),
        vSize="population",
        vColor="GNI",
        type="value",
        bg.labels = 0)

There are other options in the package to let you play with colors. But at least the label can be transparent.

To remove continent labels, you can post hoc edit the graph. The graph creates a grid object. The last two elements of this grid object appear to be country labels. Hence, you can remove them like this:



lapply(tail(grid.ls(print=FALSE)$name, 2), grid.remove)
0
