abstract: A tool to analyze and visualize toponym distributions. This package is intended
  as an interface to the GeoNames data. A regular expression filters data and in a
  second step a map is created displaying all locations in the filtered data set.
  The functions make data and plots available for further analysis—either within R
  or in a chosen directory. Users can select regions within countries, provide coordinates
  to define regions, or specify a region within the package to restrict the data selection
  to that region or compare regions with the remainder of countries. This package
  relies on the R packages `geodata` for map data and `ggplot2` for plotting purposes.
