The rstantools package provides various tools for developers of R packages interfacing with Stan, including functions to set up the required package structure, S3 generic methods to unify function naming across Stan-based R packages, and vignettes with guidelines for developers.
To get started building a package see the two rstantools vignettes for developers:
Install the latest release from CRAN
Install latest development version from GitHub (requires remotes package):
This installation from GitHub will not build the vignettes, but we recommend viewing the them online at mc-stan.org/rstantools/articles.
