Getting started

What can you get with datelife?

As a datelife user, you can get age data for your organisms of interest in several forms:

  • MRCA: Get the age of the most recent common ancestor (MRCA) of your organisms.

  • Original chronogram: Get the chronograms from the original publications, pruned to contain your organisms only.

  • Biggest chronogram: Get the original chronogram with the most organisms of interest present as tips.

  • Summary chronogram: Obtain a single chronogram, summarized using data from the original chronograms. The summary chronogram can be calculated using different methods.

You can also apply the obtained age data to date a phylogenetic tree topology of your organisms of interest.

How do you use datelife to get these data?

1. Processing your organism names

The function make_datelife_query processes the taxon names of your organisms of interest and structures them as a datelifeQuery object.

A datelifeQuery object is a list of three elements:

  • $cleaned_names: a character vector of “cleaned” taxon names,
  • $ott_ids: a numeric vector of OpenTree Taxonomic identifiers (OTT ids), and
  • $phy: an input tree as a phylo object or NA if none was provided.

This allows us to straightforwardly use the processed taxon names later to perform a search for ages across the datelife chronogram database as well as other downstream analyses.

There are two alternative ways of processing organism names with datelife:

a) From a set of organism taxonomic names

You can provide the taxon names as a character vector or as a single comma separated string of names. For example, running the following:

datelife::make_datelife_query(input = c("Delphinus_delphis",
                                        "Gallus gallus",
                                        "elephas Maximus",
                                        "felis_catus",
                                        "homo-sapiens"))
make_datelife_query output 1 
#> ... Making a DateLife query.
#> ... Phylo-processing 'input'.
#> 'input' is not a phylogeny.
#> DateLife query done!
#> $cleaned_names
#> [1] "Delphinus delphis" "Gallus gallus"     "elephas Maximus"
#> [4] "felis catus"
#>
#> $ott_ids
#> NULL
#>
#> $phy
#> [1] NA
#>
#> attr(,"class")
#> [1] "datelifeQuery"

Gives the same result as running:

datelife::make_datelife_query(input = "Delphinus_delphis,
                                       Gallus gallus,
                                       elephas Maximus,
                                       felis_catus,
                                       homo-sapiens")
make_datelife_query output 2 
#> ... Making a DateLife query.
#> ... Phylo-processing 'input'.
#> 'input' is not a phylogeny.
#> DateLife query done!
#> $cleaned_names
#> [1] "Delphinus delphis" "Gallus gallus"     "elephas Maximus"
#> [4] "felis catus"
#>
#> $ott_ids
#> NULL
#>
#> $phy
#> [1] NA
#>
#> attr(,"class")
#> [1] "datelifeQuery"

Note that you can use underscores or spaces to separate binomial scientific names and datelife will process them the same.

b) From a tree with organism taxonomic names as tip labels

You can also provide the taxon names of your organisms of interest as labels on the tips of any phylogenetic tree. You can provide the tree as a newick string:

newick <- "((Elephas_maximus,(Homo_sapiens,(Delphinus_delphis, Felis_silvestris))), Gallus_gallus);"
datelife::make_datelife_query(input = newick)
make_datelife_query output 3 
#> ... Making a DateLife query.
#> ... Phylo-processing 'input'.
#> 'input' is a phylogeny and it is correcly formatted.
#> DateLife query done!
#> $cleaned_names
#> [1] "Elephas maximus"   "Delphinus delphis" " Felis silvestris"
#> [4] " Gallus gallus"
#>
#> $ott_ids
#> NULL
#>
#> $phy
#>
#> Phylogenetic tree with 4 tips and 3 internal nodes.
#>
#> Tip labels:
#>   Elephas_maximus, Delphinus_delphis, _Felis_silvestris, _Gallus_gallus
#>
#> Rooted; no branch lengths.
#>
#> attr(,"class")
#> [1] "datelifeQuery"

You can also provide the tree as a phylo object. If you already have a tree as a phylo object, you can use that directly. For this example, we will first convert our newick string to phylo. You can do this with the function read.tree from the ape package:

phylo <- ape::read.tree(text = newick)
datelife::make_datelife_query(input = phylo)
make_datelife_query output 4 
#> ... Making a DateLife query.
#> ... Phylo-processing 'input'.
#> 'input' is a phylogeny and it is correcly formatted.
#> DateLife query done!
#> $cleaned_names
#> [1] "Elephas maximus"   "Delphinus delphis" "Felis silvestris"
#> [4] "Gallus gallus"
#>
#> $ott_ids
#> NULL
#>
#> $phy
#>
#> Phylogenetic tree with 4 tips and 3 internal nodes.
#>
#> Tip labels:
#>   Elephas_maximus, Delphinus_delphis, Felis_silvestris, Gallus_gallus
#>
#> Rooted; no branch lengths.
#>
#> attr(,"class")
#> [1] "datelifeQuery"

Now save your datelifeQuery as an object for the next section:

my_datelife_query <- datelife::make_datelife_query(input = phylo)
#> ... Making a DateLife query.
#> ... Phylo-processing 'input'.
#> 'input' is a phylogeny and it is correctly formatted.
#> DateLife query done!

2. Searching the chronogram database

The datelife_search function takes a datelifeQuery object and goes through the datelife chronogram database to find all chronograms matching at least two taxon names:

datelife::datelife_search(input = my_datelife_query)
datelife_search default output 
#> ... Running a DateLife search.
#> ... Getting a DateLife result.
#> DateLife result obtained!

3. Summarizing chronogram search results

datelife_search will also summarize results from the chronogram database search for you. By default, it will give you all original chronograms matching the search, as a phylo or multiPhylo object. You can specify the format you desire for the summary of results with the argument summary_format. There are different summary formats to choose from:

Citations

summary_format = "citations" gives back the study citations from all original chronograms matching your search:

citations <- datelife::datelife_search(input = my_datelife_query,
                          summary_format = "citations")
datelife_search output “citations”

MRCA ages

summary_format = "mrca" gives back the age of the MRCA of your organisms of interest:
