Calculate Fibonacci Numbers by Several Methods

Description

Compute Fibonacci numbers using four different methods: 1) iteratively using R code, 2) via the closed function in R code, 3) iteratively in C using the .C function, and 4) iteratively in C using the .Call function.

Usage

Arguments

n

nth fibonacci number to calculate

len

a vector of length len showing previous fibonacci numbers

method

select method to use: C, Call, R, closed
