zero_finder_nleqslv: Zero finder

In genpwr: Power Calculations Under Genetic Model Misspecification

Description

Finds zeros of multinomial functions using the nleqslv package

Usage

zero_finder_nleqslv(
  afun,
  veclength,
  tol = 0.4,
  x.start.vals = NULL,
  upper.lim = Inf
)

Arguments

afun	The function to find zeros
veclength	The dimension of the system of equations
tol	The range within which to set start values for the function to use to find zeros
x.start.vals	Optional user defined start values
upper.lim	to be used if there is to be an upper limit to the solution

Value

Predicted zeros of the given equation

Examples

afun <- function(x) {
	y <- numeric(2)
	y[1] <- x[1]^2 + x[2]^2 - 1
	y[2] <- exp(x[1]-1) + x[2]^3 - 1.1
	y
}

zero_finder_nleqslv(afun, veclength = 2)
