as.SpatialPolygonsDataFrame.recmap

as.SpatialPolygonsDataFrame

The method generates a SpatialPolygons object of a as input given
<code>recmap</code> object. Both <code>data.frame</code>s are merged by the index order.

Implements the RecMap MP2 construction heuristic
<doi:10.1109/INFVIS.2004.57>.
This algorithm draws maps according to a given statistical
value, e.g., election results, population, or epidemiological data.
The basic idea of the RecMap algorithm is that each map region,
e.g., different countries, is represented by a rectangle.
The area of each rectangle represents the statistical value given
as input (maintain zero cartographic error).
C++ is used to implement the computationally intensive tasks.
The vignette included in this package provides documentation
about the usage of the recmap algorithm.
