Fibonacci Sequence in R Programming Language

Fibonacci Sequence in R Programming

The Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones, starting from 0 and 1. In R programming, we can explore this sequence using different approaches:

• Loops: We can iterate through the sequence, calculating and storing each new term based on the previous ones.
• Recursion: We can define a function that calls itself with the previous two terms as arguments, calculating the next term in the sequence.
• Vectorized operations: We can utilize R’s built-in functions and vectorized operations to efficiently create the sequence in one go.

Program Input:

nterms = as.integer(readline(prompt="How many terms? "))
# first two terms
n1 = 0
n2 = 1
count = 2
# check if the number of terms is valid
if(nterms <= 0) {
print("Plese enter a positive integer")
} else {
if(nterms == 1) {
print("Fibonacci sequence:")
print(n1)
} else {
print("Fibonacci sequence:")
print(n1)
print(n2)
while(count < nterms) {
nth = n1 + n2
print(nth)
# update values
n1 = n2
n2 = nth
count = count + 1
}
}
}

Out put:

How many terms? 6
[1] "Fibonacci sequence:"
[1] 0
[1] 1
[1] 1
[1] 2
[1] 3
[1] 5
