+\title{Generates random number from a Gamma distribution}
+\usage{
+randga(a, b)
+}
+\arguments{
+\item{a}{shape}
+
+\item{b}{rate}
+}
+\value{
+One realization of Gamma(a, b)
+}
+\description{
+Generates one random number from shape parameter a and rate parameter b
+}
+\details{
+The generated random variable has mean a / b. It will be positively-skewed for small values, but converges to a symmetric distribution for very large numbers of a and b.
