The moultmcmc package implements a Bayesian inference framework for models of avian primary moult data.
moultmcmcExtra implements further model extensions, which are currently outside the scope of moultmcmc.
The package moultmcmcExtra is built around pre-compiled Stan models, the easiest and quickest way of installing it is to install the package from R-universe use the following code:
install.packages("moultmcmcExtra", repos = "https://pboesu.r-universe.dev")
On Mac and Windows systems this will make use of pre-compiled binaries, which means the models can be run without having to install a C++ compiler. On Linux this will install the package from a source tarball. Because of the way the Stan models are currently structured, compilation from source can be a lengthy process (several minutes), depending on system setup and compiler toolchain.
To install moultmcmcExtra from the github source (not generally recommended for Windows users) use the following code. This requires a working C++ compiler and a working installation of rstan:
#not generally recommended for Windows/MacOS users
install.packages("remotes")
remotes::install_github("pboesu/moultmcmcExtra")
