\title{Normal Quantile-Quantile Plots}


\description{
  
    Displays a normal quantile-quantile plot
}


\usage{
assetsQQNormPlot(x, col = "steelblue", skipZeros = FALSE, \dots)
}


\arguments{
  
    \item{x}{
        any rectangular time series object which can be converted by the 
        function \code{as.matrix()} into a matrix object, e.g. like an 
        object of class \code{timeSeries}, \code{data.frame}, or \code{mts}. 
        } 
    \item{col}{
        a character string, defining the color to fill the boxes.
        }
    \item{skipZeros}{
        a logical,  should zeros be skipped in the histogram plot of the
        return series?
        }
    \item{\dots}{
        optional arguments to be passed.
