malan: MAle Lineage ANalysis

An R package (https://www.r-project.org/) to perform MAle Lineage ANalysis by simulating genealogies backwards and imposing short tandem repeats (STR) mutations forwards. Intended for forensic Y chromosomal STR (Y-STR) haplotype analyses. Numerous analyses are possible, e.g. number of matches and meiotic distance to matches.

Refer to papers mentioned in citation("malan") (DOI’s: https://doi.org/10.1371/journal.pgen.1007028, https://doi.org/10.21105/joss.00684 and https://doi.org/10.1016/j.fsigen.2018.10.004).

Installation

You first need R (https://www.r-project.org/). Then you can install malan from GitHub by using the remotes package (https://CRAN.R-project.org/package=remotes):

# install.packages("remotes")
remotes::install_github("mikldk/malan")

For Mac OS users

Some Mac OSX configurations may have installation problems (for example missing gfortran libraries). In such cases, it may help to use Conda package management system. See also the discussion in issue #14.

Getting started

See documentation included in package (vignettes and manual) at https://mikldk.github.io/malan/. The introduction vignette is available at https://mikldk.github.io/malan/articles/introduction.html.

You can also get an overview of the included vignettes by the following R command:

vignette(package = "malan")

To read a vignette, type:

vignette("introduction", package = "malan")

Running tests

Note that to also install the tests, you need to install the package as follows:

# install.packages("remotes")
remotes::install_github("mikldk/malan", INSTALL_opts="--install-tests")

You can now run the tests:

library(malan)
library(testthat)
test_package('malan')
