Plots the normal inverse Gaussian Shape Triangle.


nigShapeTriangle(object, add = FALSE, labels = TRUE, ...)



an object of class "fDISTFIT" as returned by the function nigFit.


a logical value. Should another point added to the NIG shape triangle? By default FALSE, a new plot will be created.


a logical flag by default TRUE. Should the logarithm of the density be returned?


arguments to be passed to the function integrate.


displays the parameters of fitted distributions in the NIG shape triangle.
