+\title{Plots t- ES against confidence level}
+\usage{
+tESPlot2DCL(...)
+}
+\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 geometric return data
+
+ mu Mean of daily geometric return data
+
+ sigma Standard deviation of daily geometric return data
+
+ df Number of degrees of freedom in the t distribution
+
+ cl ES confidence level and must be a vector
+
+ hp ES holding period and must be a scalar}
+}
+\description{
+Plots the ES of a portfolio against confidence level, assuming that L/P is
+t distributed, for specified confidence level and holding period.
+}
+\examples{
+# Computes ES given geometric return data
+   data <- runif(5, min = 0, max = .2)
+   tESPlot2DCL(returns = data, df = 6, cl = seq(.9,.99,.01), hp = 60)
+
+   # Computes v given mean and standard deviation of return data
+   tESPlot2DCL(mu = .012, sigma = .03, df = 6, cl = seq(.9,.99,.01), hp = 40)
