letsR: Tools for data handling and analysis in macroecology

R functions for handling and analyzing geographic data, mainly species' geographic distributions (in ESRI shapefile format) and environmental variables (in raster format), as well as species' information related to their description (e.g. taxonomy and year of description) and conservation status (e.g. category of threat, population trend) as provided by the IUCN's RedList database. The package includes functions to create presence-absence matrices based on species distributions and user-defined grid systems, from which several other functions could be applied to generate, for example, species richness rasters and maps, and geographical midpoints of species. In addition, it provides a function to create spatial correlograms of variables, based on the Moran's I index, under the equiprobable or equidistant criterion to define distance classes.
