+\arguments{
+\item{...}{The input arguments contain either return data or else mean and
+ standard deviation data. Accordingly, number of input arguments is either 4
+ or 5. In case there 4 input arguments, the mean and standard deviation of
+ data is computed from return data. See examples for details.
+
+ returns Vector of daily P/L data
+
+ mu Mean of daily P/L data
+
+ sigma Standard deviation of daily P/L data
+
+ df Number of degrees of freedom in the t distribution
+
+ cl VaR confidence level and must be a vector
+
+ hp VaR holding period and must be a vector}

+\description{
+Plots the ES of a portfolio against confidence level and holding period
+assuming that P/L are Student-t distributed, for specified confidence level
+and holding period.
