# How to Apply the uniroot() Function in R (Example Code)

In this article you’ll learn how to apply the uniroot function in the R programming language.

## Creation of Example Data

f <- function(x) { # Create user-defined function in R y <- 2 * x^3 - 10 * x^2 + 50 * x - 20000 } |

f <- function(x) { # Create user-defined function in R y <- 2 * x^3 - 10 * x^2 + 50 * x - 20000 }

## Example: Get Root (Zero) of Function Using uniroot() Command

uniroot(f, interval = c(- 200, 200))$root # Find one dimensional root # [1] 22.92958 |

uniroot(f, interval = c(- 200, 200))$root # Find one dimensional root # [1] 22.92958
