## 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:

```{r, eval = FALSE}
datelife::make_datelife_query(input = c("Delphinus_delphis",
                                        "Gallus gallus",
                                        "elephas Maximus",
                                        "felis_catus",
                                        "homo-sapiens"))
```
<details>
<summary>make_datelife_query output 1</summary>
```r
#> ... 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"
```
</details>

Gives the same result as running:

```{r, eval = FALSE}
datelife::make_datelife_query(input = "Delphinus_delphis,
                                       Gallus gallus,
                                       elephas Maximus,
                                       felis_catus,
                                       homo-sapiens")
```
<details>
<summary>make_datelife_query output 2</summary>
```r
#> ... 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"
```
</details>


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:

```{r, eval = FALSE}
newick <- "((Elephas_maximus,(Homo_sapiens,(Delphinus_delphis, Felis_silvestris))), Gallus_gallus);"
datelife::make_datelife_query(input = newick)
```
<details>
<summary>make_datelife_query output 3</summary>
```r
#> ... 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"
```
</details>

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:

```{r, eval = FALSE}
phylo <- ape::read.tree(text = newick)
datelife::make_datelife_query(input = phylo)
```
<details>
<summary>make_datelife_query output 4</summary>
```r
#> ... 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"
```
</details>

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

```{r, eval = FALSE}
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:

```{r, eval = FALSE}
datelife::datelife_search(input = my_datelife_query)
```
<details>
<summary>datelife_search default output</summary>
```r
#> ... Running a DateLife search.
#> ... Getting a DateLife result.

</details>

### 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:

```{r, eval = FALSE}
citations <- datelife::datelife_search(input = my_datelife_query,
                          summary_format = "citations")
```

<!--TODO: add something about NJ, why is this happening

One can use a clustering method like Neighbor Joining (NJ). While we implemented this method in the package, because NJ are greedy algorithms they do not perform well and often return topologies that are not biologically plausible. Hence, we implement
a different workflow, -->
