Changes in version 1.47                         

  - data("a") is no longer included in the package due to its large
    size, and absence of use in the wild. See system.file("scripts",
    "readdata.R", package = "Hiiragi2013") for details on how to create
    it by downloading raw data from ArrayExpress.
  - Many dependencies have moved from Depends to Imports or Suggests.
  - NAMESPACE now uses importFrom() instead of import() whole
    namespaces.
