"Web6.1 Root Finding. R comes with the uniroot () function which can search a specified interval for a root of the target function f with respect to its first argument. To use uniroot (), one needs to specify the lower ( l) and upper ( u) bounds of the interval such that f(l)f(u) < 0. To solve the following problem: f(x) = x2 − 2x − 3 = 0. " - Solnp function in r
