GNU R projection predictive feature selection

 Performs projection predictive feature selection for generalized linear models
 (see, Piironen, Paasiniemi and Vehtari, 2018, <arXiv:1810.02406>).
 The package is compatible with the 'rstanarm' and 'brms' packages, but other
 reference models can also be used. See the package vignette for more
 information and examples.
