rDNA. A Package to Control DNA from R

This is the companion package to DNA. It integrates the Java software with the statistical computing environment R.

You can install the most recent release using:

# install.packages("remotes")
remotes::install_github("leifeld/dna/rDNA@*release", INSTALL_opts = "--no-multiarch")

This is the recommended version for most users. Note that the package relies on rJava, which needs to be installed first. For details on the installation process on different operating systems, consult the chapter "Installation of DNA and rDNA" in the manual.

To update rDNA, you can use:

# install.packages("remotes")
remotes::install_github("leifeld/dna/rDNA@*release", INSTALL_opts = "--no-multiarch")
dna_downloadJar() # update DNA as well to have matching versions

Please note that if you prefer to use the very latest version, you are required to compile the current jar file from the sources on GitHub, for example using the provided make file. Then you can install rDNA from source using:

# install.packages("remotes")
remotes::install_github("leifeld/dna/rDNA", INSTALL_opts = "--no-multiarch")
