Alternating Manifold Proximal Gradient Method for Sparse PCA uses the Alternating Manifold Proximal 
    Gradient (AManPG) method to find sparse principal components from a data or covariance matrix. Provides
    a novel algorithm for solving the sparse principal component analysis problem which provides
    advantages over existing methods in terms of efficiency and convergence guarantees.

Tools for Clustering and Principal Component Analysis
        (With robust methods, and parallelized functions).

Getting and parsing data of location geocode/reverse-geocode and administrative regions from 'AutoNavi Maps'<https://lbs.amap.com/api/webservice/summary> API.

Build and control interactive 2D and 3D maps with 'R/Shiny'.  Lean set of powerful commands wrapping native calls to 'AMap' <https://lbs.amap.com/api/jsapi-v2/summary/>.
    Deliver rich mapping functionality with minimal overhead.

Read, manipulate and write voxel spaces. Voxel spaces are
    read from text-based output files of the 'AMAPVox' software. 'AMAPVox'
    is a LiDAR point cloud voxelisation software that aims at estimating
    leaf area through several theoretical/numerical approaches. See more
    in the article Vincent et al. (2017) <doi:10.23708/1AJNMP> and the
    technical note Vincent et al. (2021) <doi:10.23708/1AJNMP>.
