Or download binaries from CRAN.
Master branch on GitHub has the release version, as available on CRAN.
If you want to install the developer version:
library(devtools)install_github(repo = 'piLaboratory/sads', ref= 'dev', build_vignettes = TRUE)
When running under Windows, you will need to install the Rtools package to build the vignettes locally.
An experimental branch implementing Lindsey's (1999) correction for the log-likelihood of continuous density distributions when used for discrete data can be installed by:
library(devtools)install_github(repo = 'piLaboratory/sads', ref= 'trueLL', build_vignettes = TRUE)
