fastbioclim: Scalable and Flexible Derivation of Custom-Time Bioclimatic and
Environmental Summary Variables
Provides an efficient tool for creating custom-time bioclimatic and derived environmental
summary variables from user-supplied raster data for user-defined timeframes. The package overcomes
computational bottlenecks by automatically switching between an in-memory framework using the 'terra'
package to maximize speed for smaller datasets, and an on-disk tiling framework for rasters that exceed
available RAM, leveraging 'exactextractr' and 'Rfast' to process data in chunks. The core functions,
derive_bioclim() and derive_statistics(), offer a unified interface with flexibility for custom time
periods beyond standard quarters and the use of fixed temporal indices, facilitating the creation of
temporally-matched environmental variables for ecological and biogeographical modeling. Visit
