uniroot_noerr: Root finding without error

In rscherrer/speciomx: Adaptive Dynamics Approximation of the Speciome Model

Root finding without error

Description

Runs the uniroot root finding algorithm and returns NULL instead of erroring if no solution is found.

Usage

uniroot_noerr(f, interval, ...)

Arguments

f	The function whose roots to find (must have one argument only)
interval	The range within which to search for a root
...	Additional parameters for uniroot

Details

The uniroot function errors if no solution is found, which is undesirable when looking for multiple roots across a range, or when looking for roots as part of a bigger pipeline. This function catches the error produced by uniroot if no solution is found and returns NULL instead.

Value

A root, or NULL

Examples

f <- function(x) x^2 - 1
uniroot_noerr(f, c(-50, -30))
