  installRepo..r -r bitbucket alexiosg/rugarch           # using  BitBucket instead
  installRepo.r -r svn https://github.com/hadley/stringr # from Subversion or a URL
  installRepo.r -r url https://cran.rstudio.com/src/contrib/Archive/digest/digest_0.5.0.tar.gz

installRepo.r is part of littler which brings 'r' to the command-line.
