See the below example to understand how to create a tree from the data frame. 

Use as.Node( ) to create tree from dataframe.

library(treemap)
data(GNI2014)
head(GNI2014)
GNI2014$pathString <- paste("world", 
                            GNI2014$continent, 
                            GNI2014$country, 
                            sep = "/")
population <- as.Node(GNI2014)
print(population, "iso3", "population", "GNI", limit = 20)

The example is taken from here, check here for more information.
