Find a single root of a function of one variable within a specified interval.

1 |

`f` |
A real function of a single variable. |

`interval` |
A vector of two real numbers defining the ends of the interval in which to search. |

`tol` |
A tolerance for the root. When the interval within which a root exists is smaller than |

`maxiter` |
A limit on the number of function evaluations permitted in the attempt to find a root. |

`trace` |
If TRUE, provided diagnostic output of the process of rootfinding. |

`...` |
Extra data needed to compute the function |

To be added.

The output is a list consisting of return(list(root=b, froot=NA, rtol=wtol, maxit=maxit)) ## Acceptable approx. is found

`root` |
The estimate, b, of the position of the root. |

`froot` |
The value of the function at this point, f(b). |

`rtol` |
The width of the interval in which the root exists. |

`fcount` |
The number of function evaluations used. |
