treestartr: A package for generating reasonable starting trees for phylogenetic analysis.

Description

treestartr provides multiple ways to add tips to a starting tree

treestartr functions

absent_tippr, echo_rb, echo_subtree, present_tippr, rand_absent_tippr, text_placr

Add tips to tree via user input

Description

Add tips not on existing tree to the tree via user input, if they do not have congeners on the tree. This function will generate a tree, with nodes numbered. For each tip to be added, the user will be asked #' to enter the number of the node they would like the tip to subtend.

Usage

absent_tippr(tree, absent_list)

Arguments

Value

tree Phylo object containing the starting tree, and all tips that were added.

Examples

## Not run:  new <- absent_tippr(tree, absent_list) 

bears

Description

A dataset containing 18 taxa and 62 characters for bears

Usage

data(bears)

Format

A collection of objects representing function inputs:

tax_frame

a two-column dataframe of taxon names and ages

absent_list

A list of taxa in the total data set, but are not on the tree

mrca_df

a two-column dataframe of taxa to be placed, and a set of taxa that indicate the MRCA which they will subtend

tree

A phylogenetic tree to which tips will be added

Detect file format of taxon file

Description

Detect file format of the total taxon list (molecular, morphological, and stratigraphic) and maximum age of fossil, see RevBayes total -evidence fossil file for an example of this.

Usage

dataf_parsr(dataf)

Arguments

Value

tax_frame Dataframe containing the total set of tips on the tree

Examples

## Not run: tax_frame <- dataf_parsr(dataf)

Print RevBayes-formatted clade constriants.

Description

Once a tip has been added to the tree, print the subtree to which the tip was added. The output of this function is printed for use as a RevBayes clade constraint object.

Usage

echo_rb(tree, mrca_list, tip)

Arguments

Value

vector A comma-separated list of all the taxa in the subtree to which the tip was added.

Examples

 mrca_list <- c("Ursus_arctos", "Ursus_spelaeus", "Ursus_americanus")
clade_constraint <- echo_rb(tree, mrca_list, "Ursus_abstrusus")

Print subtrees with tips added.

Description

Once a tip has been added to the tree, print the newick-formatted subtree to which the tip was added.

Usage

echo_subtree(tree, mrca_list, tip)

Arguments

Value

tree subtree to which tip was added

Examples

mrca_list <- c("Ursus_arctos", "Ursus_spelaeus", "Ursus_americanus")
tree <- text_placr(tree, mrca_df)
echo_sub <- echo_subtree(tree, mrca_list, "Ursus_abstrusus")

Utility function to check if file is a csv or tsv.

Description

Utility function to check if file is a csv or tsv.

Usage

fileformat(dataf)

Arguments

Value

None

Check if tip is on tree

Description

Test which taxa in the total set of taxa are present on the tree, and which need to be added. The tax_frame object is assumed to be a dataframe, minimally with a column labeled "taxon". If this column does not exist, the first column in the dataframe will be assumed to contain the taxon information.

Usage

genera_strippr(tree, tax_frame)

Arguments

Value

absent_list of taxa that are present in the total set of trees, but not the starting tree

Examples

absent_taxa <- genera_strippr(tree, tax_frame = tax_frame)

Get dataframe of tips that do not have congeners on tree.

Description

Determine which tips that are not on the tree, and checks if they have congeners on the tree.

Usage

get_found(absent_list, tree)

Arguments

Value

found_df Dataframe objects expressing the tips that are not on the tree, if they have congeners on the tree

Examples

has_congeners <- treestartr:::get_found(absent_list, tree)

Determine if a tip is present on a tree

Description

Determine which tips that are not on the tree, puts them in a dataframe if they do not have congeners on the tree

Usage

get_lost(absent_list, tree)

Arguments

Value

not_found_df Dataframe objects expressing the tips that are not on the tree, and don"t have congeners

Examples

no_congeners <- treestartr:::get_lost(absent_list, tree)

Determine which tips are not on the tree, and get their genera.

Description

Determine which tips are not on the tree, and get their genera.

Usage

make_absentdf(absent_list)

Arguments

Value

absent_df Dataframe objects expressing which tips are in the total set but not the tree, and their genera

Examples

not_present <- treestartr:::make_absentdf(absent_list)

Determine which tips are on the tree, and get their genera.

Description

Determine which tips are on the tree, and get their genera.

Usage

make_treedf(tree)

Arguments

Value

tree_df Dataframe objects expressing the tips, and their genera

Add tips to the tree based on taxonomy.

Description

Add tips not on existing tree to the tree via an MRCA node, if they have congeners. This function will look to see if any tips on the tree have the same genus as the tip to be added. If there are multiple members of the genus, the tip will be added subtending the MRCA of all present congeners. If there is member of the genus, the tip will be added subtending the parent node of the congener.

Usage

present_tippr(tree, absent_list, echo_subtrees = NULL,
  echo_revbayes = NULL)

Arguments

Value

tree. Phylo object containing the starting tree, and all tips that were added.

Examples

genera_tree <- present_tippr(tree, absent_list)

Random addition of taxa

Description

Add tips not on existing tree to the tree at random, if they do not have congeners on the tree.

Usage

rand_absent_tippr(tree, absent_list, echo_subtrees = NULL,
  echo_revbayes = NULL)

Arguments

Value

tree Phylo object containing the starting tree, and all tips that were added.

Examples

new_tree <- rand_absent_tippr(tree, absent_list)

Utility function to check taxon_names in parsed data file

Description

Utility function to check taxon_names in parsed data file

Usage

taxon_testr(tax_frame)

Arguments

Value

None

Add tips to tree via taxon list

Description

Add tips according to csv or tsv file of taxon names and taxa that form the clade into which you"d like to insert the tip. One column should be called 'taxon', and should contain the taxon to be placed. The other column should be called 'clade' and contain the taxon with which the taxon to be placed will form a group. Each member of the clade will be placed on its own line. An example of this file can be seen in 'inst/extdat a/mrca_df.tsv'

Usage

text_placr(tree, mrca_df, echo_subtrees = NULL, echo_revbayes = NULL)

Arguments

Value

tree Phylo object containing the starting tree, and all tips that were added.

Examples

text_placr(tree, mrca_df)
