How to skip shortcuts in R treemap?

I used the R treemap package , and I have a treemap that is on 2 levels. I want second-level labels printed, but not the first.

Using the example on the manual page:

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

example map card http://www.eecs.tufts.edu/~rveroy/stuff/GNI2010-treemap.png

I want to get rid of the labels of the continents, but keep the iso3 labels. I apologize in advance if it is in the documents, but did not find it.

To remove the labels of the continents, you can publish hoc to edit the graph. The graph creates a grid object. The last two elements of this grid object appear as country labels. Therefore, you can remove them as follows:

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

Another option is to reduce the font size that the fonts you want to see disappear. For instance,

 tmPlot(GNI2010, index=c("continent", "iso3"), vSize="population", vColor="GNI", type="value", fontsize.labels=c(0,10))

only the initial value will be displayed for countries, not for continents.
