Package letsR

This package provides different functions for data handling and analysis in macroecology. It is being developed at LETS (Laboratório de Ecologia Teórica e Síntese) in UFG (Universidade Federal de Goiás, Brazil) as part of a larger project looking to integrate recent advances in macroecological data handling and processing. Its purpose is to make some of our commonly used but unavailable R functions available to the larger public. The package provides useful R functions for researchers in ecology and evolution.

The letsR package is in continuous development and suggestions are more than welcome!

We hope you enjoy it and find it useful.

====

Install

Install letsR from CRAN

install.packages("letsR")
library("letsR")

Install letsR developers version from github

install.packages("devtools")
library(devtools)
install_github("macroecology/letsR")
library(letsR)

OBS.: To download the developers version you will need to have the git software installed (http://git-scm.com/). If you are a windows user you will also need to download the Rtools (http://cran.r-project.org/bin/windows/Rtools/).

Key functions

The letsR package includes many different functions. Below we highlight some them:

• lets.presab: Builts a presence-absence matrix (sites x species) based on species’ range maps from shapefiles.
• lets.presab.birds: Builts a presence-absence matrix (sites x species) based on species’ range maps from shapefiles (specially designed for the BirdLife International database).
• lets.shFilter: Filter species’ shapefiles by origin, presence and seasonal type (following IUCN categorization of species’ distributional ranges).
• lets.addvar: Add variables in raster format to a presence-absence matrix.
• lets.addpoly: Add variables in polygon format to a presence-absence matrix.
• lets.iucn: Get species’ information from the IUCN website (different from taxize version).
• lets.iucn.ha: Get species’ habitat information from the IUCN website.
• lets.iucn.his: Get information on the history of species’ conservation status from the IUCN website.
