The goal of rtrees is to remove the barriers to derive phylogenies for
a list of species from mega-trees. Basically, Phylomatic and more.
options(repos = c(
rtrees = 'https://daijiang.r-universe.dev',
CRAN = 'https://cloud.r-project.org'))
install.packages("rtrees")The above code will also install one dependency {megatrees}, an R data package that hosts the megatrees used here.
There is also a Shinny app to get phylogenies without using R. However, given that I can only afford the free plan, the number of species to be inserted to the megatrees here will be limited to 1,000.
Currently, rtrees provides mega-trees for the following taxonomic
groups: amphibian, bird, fish, mammal, plant, reptile, and shark_ray.
The mega-trees (or subset of 100 posterior phylogenies; 50 for fish to
reduce the package size) are saved in the data package
{megatrees}.

#> Warning: package 'rtrees' was built under R version 4.3.3
library(ape)The species lists which we want to have a phylogeny should be provided
as a data frame with at least 3 columns: family, genus, and
species. Their order does not matter. Here is an example for fish.
test_fish_list = tibble::tibble(
species = c("Serrasalmus_geryi", "Careproctus_reinhardti", "Gobiomorphus_coxii",

with function sp_list_df(); though you should check the results. It is
possible to just provide the speices as a character vector for these
taxon groups (or all genus in your species list are presented in the
phylogeny).

test_tree = get_tree(sp_list = test_fish_list,
taxon = "fish",
scenario = "at_basal_node",
show_grafted = TRUE)

No matter whether show_grafted is ‘TRUE’ or ‘FALSE’, the grafting
information was saved along with the phylogeny and can be extracted with
the following code:

#> 12 <NA> Barathronus_bicolor skipped as no co-family in …The function rtrees::get_tree() can also work with a set of posterior
megatrees with the option to use parallel computing for the whole
process. The default number of cores to be used will be the available
number of cores minus 2 (so that users can still perform other tasks on
their computers at the same time). The output will be a set of generated
phylogenies with class multiPhylo; the number of derived phylogenies
will be the same as the input megatrees. For this scenario, we can use
exactly the same code described above. For example, if we want to use
the 100 randomly selected posterior phylogenies that have ~32k fish
species, we can add the fish_tree = "all-taxon.
test_tree2 = get_tree(sp_list = test_fish_list,
taxon = "fish",
scenario = "at_basal_node",
show_grafted = TRUE,
fish_tree = "all-taxon")
#> Wow, all species are already in the mega-tree!
test_tree2
#> 50 phylogenetic trees
plot(ladderize(test_tree2[[1]]), no.margin = T)
It is also possible to derive a phylogeny based on a user provided tree.
This can be particularly useful if we have things like Acer_spp that
we want to insert to the basal node of the genus.

Pay attention to the warning message there. Because not all genera in the species list are presented in the megatree, it is impossible to find the most recent ancestor for genus and family that are missing from the megatree. Therefore, for user-provided phylogenies, here is the recommended steps:
- Get the classification information (a data frame with two columns: genus and family) for all genera presented in the species list and the megatree.
- Prepare the species list as a data frame with three columns: species, genus, and family using the classification information.
- Process the megatree using function
processed_tree = rtrees::add_root_infor(tree, classification). - Pass the processed megatree to
rtrees::get_tree(sp_list_data_frame, processed_tree)to derive the phylogeny for your species list.
It is also possible to specify a particular species to bind with by
specifying columns close_sp and/or close_genus.
test_tree_sp_df = sp_list_df(test_tree_sp, "plant")
test_tree_sp_df$close_sp = NA
test_tree_sp_df$close_sp[1] = "Rosa_acicularis" # bind Rosa_sp to here
