%description
Calculate Predictive Moran's Eigenvector Maps (pMEM) for
spatially-explicit prediction of environmental variables, as defined by
Guénard and Legendre (2024) <doi:10.1111/2041-210X.14413>. pMEM extends
classical MEM by enabling interpolation and prediction at unsampled
locations using spatial weighting functions parameterized by range (and
optionally shape). The package implements multiple pMEM types (e.g.,
exponential, Gaussian, linear) and features a modular architecture that
allows programmers to define custom weighting functions. Designed for
ecologists, geographers, and spatial analysts working with
spatially-structured data.
