\title{NIG Shape Triangle}
\description{
Plots the normal inverse Gaussian Shape Triangle.
}
\usage{
nigShapeTriangle(object, add = FALSE, labels = TRUE, \dots)
}
\arguments{
\item{object}{
an object of class \code{"fDISTFIT"} as returned by the function
\code{nigFit}.
}
\item{add}{
a logical value. Should another point added to the NIG
shape triangle? By default FALSE, a new plot will be created.
}
\item{labels}{
a logical flag by default \code{TRUE}.
Should the logarithm of the density be returned?
}
\item{\dots}{
arguments to be passed to the function \code{integrate}.
}
}
\value{
displays the parameters of fitted distributions in the
NIG shape triangle.
