apex implements new classes and methods for analysing DNA sequences from multiple genes. It implements new classes extending object classes from ape and phangorn to store multiple gene data, and some useful wrappers mimicking existing functionalities of these packages for multiple genes. This document provides an overview of the package's content.
To install the development version from github:
library(devtools)
install_github("thibautjombart/apex")
The stable version can be installed from CRAN using:
install.packages("apex")
Then, to load the package, use:
library("apex")
Two simple functions permit to import data from multiple alignements into multidna
objects:
Both functions rely on the single-gene counterparts in ape and accept the same arguments. Each file should contain data from a given gene, where sequences should be named after individual labels only. Here is an example using a dataset from apex:
## get address of the file within apex
files <- dir(system.file(package="apex"),patter="patr", full=TRUE)
## read these files
x <- read.multiFASTA(files)

Two new classes of object extend existing data structures for multiple genes:
DNAbin
class, useful for distance-based trees.phyDat
class, useful for likelihood-based and parsimony trees.
Conversion between these classes can be done using multidna2multiPhydat
and multiPhydat2multidna
.This formal (S4) class can be seen as a multi-gene extension of ape's DNAbin
class.
Data is stored as a list of DNAbin
objects, with additional slots for extra information.
The class definition can be obtained by:
getClassDef("multidna")
## Class "multidna" [package "apex"]
##
## Slots:
##
## Name: dna labels n.ind n.seq n.seq.miss
## Class: listOrNULL character integer integer integer
##
## Name: ind.info gene.info
## Class: data.frameOrNULL data.frameOrNULL
##
## Extends: "multiinfo"
DNAbin
matrices, each corresponding to a given gene/locus, with matching rows (individuals)@dna
)Any of these slots can be accessed using @
, however accessor functions are available for most and are preferred (see examples below).
New multidna
objects can be created via different ways:
new("multidna", ...)
multiphyDat
object using multidna2multiphyDat
We illustrate the use of the constructor below (see ?new.multidna
) for more information.
We use ape's dataset woodmouse, which we artificially split in two 'genes', keeping the first 500 nucleotides for the first gene, and using the rest as second gene. Note that the individuals need not match across different genes: matching is handled by the constructor.

Like multidna
and ape's DNAbin
, the formal (S4) class multiphyDat
is a multi-gene extension of phangorn's phyDat
class.
Data is stored as a list of phyDat
objects, with additional slots for extra information.
The class definition can be obtained by:
getClassDef("multiphyDat")
## Class "multiphyDat" [package "apex"]
##
## Slots:
##
## Name: seq type labels n.ind n.seq
## Class: listOrNULL character character integer integer
##
## Name: n.seq.miss ind.info gene.info
## Class: integer data.frameOrNULL data.frameOrNULL
##
## Extends: "multiinfo"
phyDat
objects, each corresponding to a given gene/locus, with matching rows (individuals); unlike multidna
which is retrained to DNA sequences, this class can store any characters, including amino-acid sequences @dna
)Any of these slots can be accessed using @
(see example below).
As for multidna
, multiphyDat
objects can be created via different ways:
new("multiphyDat", ...)
multidna
object using multiphyDat2multidna
As before, we illustrate the use of the constructor below (see ?new.multiphyDat
) for more information.

object using getTree
## make trees, default parameters
trees <- getTree(x)
trees

plot(trees, 4, type="unrooted")
As an alternative, all genes can be pooled into a single alignment to obtain a single tree using:
##
## Phylogenetic tree with 8 tips and 6 internal nodes.
##
## Tip labels:
## 2340_50156.ab1 , 2340_50149.ab1 , 2340_50674.ab1 , 2370_45312.ab1 , 2340_50406.ab1 , 2370_45424.ab1 , ...
##
## Unrooted; includes branch lengths.
It is also possible to use functions from phangorn
to estimate with maximum likelihood trees.
Here is an example using the multiphyDat
object z
created in the previous section:
## input object
z
## build trees
pp <- pmlPart(bf ~ edge + nni, z, control = pml.control(trace = 0))
pp
## convert trees for plotting
trees <- pmlPart2multiPhylo(pp)
plot(trees, 4)
The following functions enable the export from apex to other packages:
genind
object; alternatively, Multi-Locus Sequence Type (MLST) can be used to treat genes as separate locus and unique sequences as alleles.This is illustrated below:
## find source files in apex

The MLST option can be useful for a quick diagnostic of diversity amongst individuals. While it is best suited to clonal organisms, we illustrate this procedure using our toy dataset:
obj3 <- multidna2genind(x, mlst=TRUE)
obj3

##
## // 8 individuals; 4 loci; 27 alleles; size: 26.8 Kb
##
## // Basic content
## @tab: 8 x 27 matrix of allele counts
## @loc.n.all: number of alleles per locus (range: 6-8)
## @loc.fac: locus factor for the 27 columns of @tab
## @all.names: list of allele names for each locus
## @ploidy: ploidy of each individual (range: 1-1)
## @type: codom
## @call: df2genind(X = xdfnum, ind.names = x@labels, ploidy = 1)
