\title{Solve the yield rate by the equation of value}
\usage{
solve_yield(cf, t, interval = c(-0.99, 1), tol = 1e-10)
}
\arguments{
\item{cf}{Cash flows.}

\item{t}{Times.}

\item{interval}{Two-length numeric vector bracketing the root.}

\item{tol}{Tolerance passed to uniroot.}
}
\value{
Yield rate i.
}
\description{
Finds the interest rate i such that the present value of the cash flows is 0.
}
\examples{
solve_yield(c(-100, 60, 60), c(0, 1, 2), interval = c(-0.5, 1))
}
