strip.spec: Extract Genus Name from Linnean Binomial

In heibl/megaptera: MEGAPhylogeny Techniques in R

Description

Strips the epitheton from a Linnean binomial and return the genus name.

Usage

strip.spec(x, mode = "strsplit")

Arguments

x	A vector of mode "character" containing Linnean binomials. The separating character can be space (" ") or underscore ("_").
mode	A vector of mode "character" chosing between two algorithms: "strsplit" is fast, but has failed on avery large vector (> 170000 element); "regex" is not as fast, but has handled also large vectors successfully.

Value

A vector of mode "character" containing genus names.

Examples

strip.spec("Megaptera_novaengeliae")

## separating characters cannot be mixed!
spec <- c("Megaptera_novaengeliae", "Megaptera novaeangliae")
strip.spec(spec) # does not work
strip.spec(gsub("_", " ", spec)) # this works
strip.spec(gsub(" ", "_", spec)) # this works
