Flexible Pycnophylactic Interpolation to Discrete Global and Local Grid Systems R package pycnogrid version 0.2.0 Provides tools for pycnophylactic interpolation of polygon totals to discrete global and local grid systems. The method follows Tobler (1979) <doi:10.1080/01621459.1979.10481647>, preserving source-zone totals while smoothing values across neighboring target cells.
