Provides a minimal, light-weight set of tools for producing nice looking maps in R, with support for map projections.  See Brown (2016) <doi:10.32614/RJ-2016-005>.

Visualise admixture as pie charts on a projected map, admixture as traditional structure barplots or facet barplots, and scatter plots from genotype principal components analysis. A 'shiny' app allows users to create admixture maps interactively. Jenkins TL (2024) <doi:10.1111/1755-0998.13943>.

Topological data analysis (TDA) is a method of data analysis that 
  uses techniques from topology to analyze high-dimensional data. Here we
  implement Mapper, an algorithm from this area developed by Singh, Mémoli and 
  Carlsson (2007) which generalizes the concept of a 
  Reeb graph <https://en.wikipedia.org/wiki/Reeb_graph>. The output graph is 
  able to be visualized in R using 'igraph' or using a free network analysis 
  software called 'Cytoscape', available for download from at 
  <https://cytoscape.org/>.

The Mapper algorithm from Topological Data Analysis, the steps are as follows 1. Define a filter (lens) function on the data. 2. Perform clustering within each level set. 3. Generate a complex from the clustering results.

Maps are an important tool to visualise variables distribution across different spatial objects. The mapping process requires to link the data with coordinates and then generate the correspondent map. This package provide coordinates, linking and mapping functions for an automatic, flexible and easy approach of external functions. The package provides an easy, flexible and automatic unit. Geographical coordinates are provided in the package and automatically linked with the input data to generate maps with internal provided functions or external functions. Provide an easy, flexible and automatic approach to potentially download updated coordinates, to link statistical units with coordinates and to aggregate variables based on the spatial hierarchy of units. The object returned from the package can be used for thematic maps with the build-in functions provided in mapping or with other packages already available.
