rglobi vignette - an R interface to the aggregated biotic interaction data of GloBI (http://globalbioticinteractions.org)

About the package

rglobi allows easy access to the GLoBI database by wrapping the existing API.


Quick start

First, install rglobi

For released version, use:

install.packages("rglobi")

For most recent development version, use:

install.packages("devtools")
## 
## The downloaded binary packages are in
##  /var/folders/v4/0_y78_xj1x7b72l89cwc2kq80000gp/T//RtmpF6qc1T/downloaded_packages
devtools::install_github("ropensci/rglobi")

## Installing rglobi

## Reloading installed rglobi
library("rglobi")

Note that since rglobi is still pretty new, only the dev version of the library is available at this time. We hope to publish a version to CRAN once the library matures. For more information see GitHub.

Find interactions involving a certain species

Determining which species interact with each other (and how and where) is a major focus of ecology. The Global Biotic Interactions Database offers data on multiple interaction types, and the rglobi library offers several ways to specify and access these interactions. get_interactions() is the primary function used if data on a specific interaction type is required. A focus taxon is entered (may be specified as “Genus species” or higher level (e.g., Genus, Family, Class)).

hsapiens <- get_interactions(taxon = "Homo sapiens", interaction.type = "preysOn")

get_predators_of() and get_prey_of() are wrappers for get_interactions() that remove the need to specify interaction type

For data sources in which type of interactions was not specified, the interaction is labeled “interacts_with”.

If you wish to view all interactions instead of specific types (e.g., parasitism and predation instead of just one of the two), the get_interactions_by_taxa() function allows this. In addition, the function provides options to search for interactions between two groups (source and target taxa, see above table) and only find interactions in a certain region.

Only a source taxa need be identified, but you can also specify a target taxon and/or geographic boundary (Coordinates must be in decimal degrees (EPSG:4326) and correspond to the west, south, east, and northern boundaries (i.e., min x, min y, max x, max y).

Find interactions in a geographic areas

Instead of a taxon-specific approach, users may also wish to gather information on all interactions occuring in a specific area. For example, a group developing ecoystem models for the Gulf of Mexico may want to consider all the data from that region. rglobi enables this type of search by allowing users to specify a rectangular bounding box. Coordinates must be in decimal degrees (EPSG:4326) and correspond to the west, south, east, and northern boundaries (i.e., min x, min y, max x, max y).

Custom Queries using Cypher

Currently, GloBI is powered by neo4j, a graph database. Most results created by the R functions provided by rglobi are basically wrappers for commonly used cypher queries. This way, you can still use the library without having to learn Cypher, a graph query language. However, if you feel adventurous, you can execute queries using Cypher only using the function query():

result <- query("START taxon = node:taxons(name='Homo sapiens') MATCH taxon<-[:CLASSIFIED_AS]-predator-[:ATE|PREYS_ON]->prey-[:CLASSIFIED_AS]->preyTaxon RETURN distinct(preyTaxon.name) as `prey.taxon.name` LIMIT 10")
result
##         prey.taxon.name
## 1          Homo sapiens
## 2    Macropus bernardus
## 3             Mysticeti
## 4   Dendrolagus scottae
## 5   Engraulis japonicus
## 6         Sergia lucens
## 7       Martes melampus
## 8   Lophocebus albigena
## 9            Salmonidae
## 10 Moschus chrysogaster

This particular query returns the names of the first ten known prey or diet items of humans (Homo sapiens). More examples of GloBI specific Cypher queries can be found on the GloBI Cypher Wiki.
