dicreteRoot: Dichotomic search for monotone function
In bozenne/riskRegressionLight: Light version of the package riskRegression

Find the root of a monotone function on a discrete grid of value using dichotomic search

1 2	discreteRoot(fn, grid, increasing = TRUE, check = TRUE, tol = .Machine$double.eps^0.5)

`fn`	[function] objective function to minimize in absolute value.
`grid`	[vector] possible minimizers.
`increasing`	[logical] is the function fn increasing?
`check`	[logical] should the program check that fn takes a different sign for the first vs. the last value of the grid?
`tol`	[numeric] the absolute convergence tolerance.
