calcFib function

Calculate Fibonacci Numbers by Several Methods

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.

calcFib(n, len=1, method="C")

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

Returns

Vector of the last len Fibonacci numbers calculated.
