Information of the centroids and geographical limits of the regions, departments, provinces and districts of Peru.

Local adaptation and evaluation of maps of continuous attributes in raster format by use of point location data.

Automated calculation and visualization of survey data statistics on a color-coded (choropleth) map.

To create maps from tiles, 'maptiles' downloads, composes and
    displays tiles from a large number of providers (e.g. 'OpenStreetMap',
    'Stadia', 'Esri', 'CARTO', or 'Thunderforest').

Maximum a posteriori (MAP) estimation for topic models (i.e., Latent Dirichlet Allocation) in text analysis,
	as described in Taddy (2012) 'On estimation and selection for topic models'.  Previous versions of this code were included as part of the 'textir' package.  If you want to take advantage of openmp parallelization, uncomment the relevant flags in src/MAKEVARS before compiling.

Functions with example data for graphing, pruning, and
        mapping models from hierarchical clustering, and classification
        and regression trees.

Quickly and conveniently create interactive
    visualisations of spatial data with or without background maps.
    Attributes of displayed features are fully queryable via pop-up
    windows. Additional functionality includes methods to visualise true-
    and false-color raster images and bounding boxes.

Focus-glue-context (FGC) fisheye transformations to two-dimensional coordinates and spatial vector geometries. Implements a smooth radial distortion that enlarges a focal region, transitions through a glue ring, and preserves outside context. Methods build on generalized fisheye views and focus+context mapping. For more details see Furnas (1986) <doi:10.1145/22339.22342>, Furnas (2006) <doi:10.1145/1124772.1124921> and Yamamoto et al. (2009) <doi:10.1145/1653771.1653788>.

Policy evaluation using generalized Qini curves: Evaluate data-driven treatment
            targeting rules for one or more treatment arms over different budget
            constraints in experimental or observational settings under unconfoundedness.
