We are building a taxonomic toolbelt for R called taxize – which gives you programmatic access to many sources of taxonomic data on the web. We just pushed a new version to CRAN (v0.1.5) with a lot of changes (see here for a rundown). Here are a few highlights of the changes.
Note: the windows binary may not be available yet…
Install and load taxize
install.packages("taxize")
library(taxize)
Taxonomic identifiers
Each taxonomic service has their own unique ID for a taxon. We had a way to get ITIS and NCBI identifiers before – we now have functions for Tropicos, EOL, and the Catalogue of Life.
get_tpsid(sciname = "Helianthus petiolaris patens") ## 1 ## 50140022 ## attr(,"class") ## [1] "tpsid" get_colid(sciname = "Pinus contorta") ## 1 ## "14376216" ## attr(,"class") ## [1] "colid"
And we have a new function to get identifiers across all sources. And it's vectorized so you can pass in many names.
get_ids(names = c("Chironomus riparius", "Poa annua"), db = c("ncbi", "itis"))
## $ncbi
## Chironomus riparius Poa annua
## "315576" "93036"
## attr(,"match")
## [1] "found" "found"
## attr(,"class")
## [1] "uid"
##
## $itis
## Chironomus riparius Poa annua
## "129313" "41107"
## attr(,"match")
## [1] "found" "found"
## attr(,"class")
## [1] "tsn"
##
## attr(,"class")
## [1] "ids"
Taxonomic classifications
We had a function called classification to get a taxonomic hierarchy from a particular source, ITIS or NCBI. We now have functions for Tropicos, EOL, and the Catalogue of Life. In addition, we have a function to get classifications across sources.
out <- get_ids(names = "Poa annua", db = c("ncbi", "itis"))
classification(out)

Synonyms
Just like the classification function, synonyms now searches across sources for synonym names. However, this function only has methods for ITIS and Tropicos.
synonyms(c("Poa annua", "Pinus contorta", "Puma concolor"), db = "itis")
## $`Poa annua`
## name tsn
## 1 Poa annua var. aquatica 538978
## 2 Poa annua var. reptans 538979

Common names from scientific names and vice versa
We have a variety of ways to get common names from scientific names for different sources. To simply things, there are two new functions to work across sources.
sci2comm(scinames = "Helianthus annuus", db = "itis") ## $`Helianthus annuus` ## comname lang tsn ## 1 common sunflower English 36616 ## 2 sunflower English 36616 ## 3 wild sunflower English 36616 ## 4 annual sunflower English 36616
And vice versa
comm2sci(commnames = "annual blue grass", db = "tropicos") ## $`annual blue grass` ## NameId ScientificName ScientificNameWithAuthors Family ## 1 25509881 Poa annua Poa annua L. Poaceae ## RankAbbreviation NomenclatureStatusID NomenclatureStatusName Symbol ## 1 sp. 1 Legitimate ! ## Author DisplayReference DisplayDate TotalRows ## 1 L. Sp. Pl. 1: 68 1753 1
ITIS functions
We reworked the functions that interact with the ITIS service. We still have all the same functions, but there are now a number of higher level functions that make the interface to ITIS simpler. Here are some examples:
Get references associated with names.
