The R package adhoc is available on the comprehensive R archive network (CRAN): http://cran.r-project.org/
Alternatively, a detailed manual, the script of both functions described in Sonet et al. (2013) and an example file (to rename "input.fas" in order to use it as the reference dataset) can be downloaded hereunder.
