Create a Slick class object — Slick-class • Slick

The Slick class is the main object class used in the Slick package. It contains sub-objects for the management procedures MPs(), operating models OMs(), and the six chart types: Boxplot(), Kobe(), Quilt(), Spider(), Timeseries(), and Tradeoff(), as well as metadata information for the Slick object such as Title, Author, and Introduction.

Usage

  Title = "",
  Subtitle = "",
  Date = Sys.Date(),
  Author = "",
  Email = "",
  Institution = "",
  Introduction = "",
  MPs = NULL,
  OMs = NULL,
  Boxplot = NULL,
  Kobe = NULL,
  Quilt = NULL,
  Spider = NULL,
  Timeseries = NULL,
  Tradeoff = NULL
)

Title(object, lang = "en", markdown = FALSE)

Title(object) <- value

Subtitle(object, lang = "en", markdown = FALSE)
