hivtree

Phylogenetic Tree of 193 HIV-1 Sequences

Description

This data set describes an estimated clock-like phylogeny of 193 HIV-1 group M sequences sampled in the Democratic Republic of Congo.

Usage

data(hivtree.newick)
data(hivtree.table)

Format

hivtree.newick is a string with the tree in Newick format. The data frame hivtree.table contains the corresponding internode distances.

Source

This is a data example from Strimmer and Pybus (2001).

Examples

# example tree in NH format (a string)
data("hivtree.newick") 
hivtree.newick

# generate file "hivtree.phy" in working directory
cat(hivtree.newick, file = "hivtree.phy", sep = "\n")
tree.hiv <- read.tree("hivtree.phy") # load tree
unlink("hivtree.phy") # delete the file "hivtree.phy"

plot(tree.hiv)

# table with list of internode distances
data("hivtree.table") 
hivtree.table


# construct coalescence intervals
ci <- coalescent.intervals(tree.hiv) # from tree
ci <- coalescent.intervals(hivtree.table$size) #from intervals
