brranching - an interface to phylogenetic data

Description

Brranching is an interface to many different sources of phylogenetic data (currently only from Phylomatic, but more sources to come). It is used to query for phylogenetic data using taxonomic names and can be used to visualise the evolutionary history and relationships among individuals or groups of organisms.

Installation

Stable CRAN version

install.packages("brranching")

Or dev version

install.packages("devtools")
devtools::install_github("ropensci/brranching")

library("brranching")

Phylomatic

Query Phylomatic for a phylogenetic tree.

taxa <- c("Poa annua", "Phlox diffusa", "Helianthus annuus")
tree <- phylomatic(taxa=taxa, get = 'POST')
plot(tree, no.margin=TRUE)

You can pass in up to about 5000 names. We can use taxize to get a random set of plant species names.

library("taxize")
spp <- names_list("species", 200)
out <- phylomatic(taxa = spp, get = "POST")
plot(out, show.tip.label = FALSE)

Bladj

library("phylocomr")
ages_df <- data.frame(
  a = c('malpighiales','eudicots','ericales_to_asterales','plantaginaceae',
        'malvids', 'poales'),
  b = c(81, 20, 56, 76, 47, 71)
)
phylo_file <- system.file("examples/phylo_bladj", package = "phylocomr")
phylo_str <- readLines(phylo_file)
x <- rbladj(tree = phylo_str, ages = ages_df)
library(ape)
plot(x)
