This function draws a treemap of labour relations (http://historicallabourrelations.org). It is a convenience wrapper for the Treemap package by Martijn Tennekens. Before this function is used, data should be setup in a specific data format (see read.lar()).
This package is intended for researchers studying historical labour relations (see http://www.historyoflabourrelations.org). The package allows for easy access of excel files in the standard defined by the Global Collaboratory on the History of Labour Relations. The package also allows for visualisation of labour relations according to the Collaboratory's format.
