An R package (https://www.r-project.org/) to perform inference in a mixture of discrete Laplace distributions using the EM algorithm. Intended for forensic Y chromosomal STR (Y-STR) haplotype analyses.

See documentation included in package (vignettes and manual) at https://mikldk.github.io/disclapmix/.

Installation

You first need R (https://www.r-project.org/). Then you can install disclapmix from CRAN using

install.packages("disclapmix")

You can also install the development version from GitHub by using the remotes package (https://CRAN.R-project.org/package=remotes):

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

Getting started

Refer to the included vignettes. You can get an overview of the included vignettes by the following R command:

vignette(package = "disclapmix")

To read a vignette, type:

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

Running tests

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

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

You can now run the tests:

library(disclapmix)
library(testthat)
test_package('disclapmix')
