letsR: Tools for data handling and analysis in macroecology.
Description
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. The letsR package is in continuous
development and suggestions are more than welcome! We hope
you enjoy it and find it useful.Details
