Calculate nCr value in R Programming - choose() Function Last Updated : 01 Jun, 2020 Comments Improve Suggest changes Like Article Like Report R Language offers a direct function that can compute the nCr value without writing the whole code for computing nCr value. Syntax: choose(n, r) Parameters: n: Number of elements r: Number of combinations Returns: The number of r combinations from a total of n elements, i.e, nCr value. Example 1: Python3 # R program to calculate nCr value # Using choose() method answer1 <- choose(3, 2) answer2 <- choose(3, 7) answer3 <- choose(7, 3) print(answer1) print(answer2) print(answer3) Output: 3 0 35 Example 2: If we provide the value of n and r such that n < r then choose(n, r) will return 0. Python3 # R program to calculate nCr value # Using choose() method answer1 <- choose(2, 3) answer2 <- choose(3, 6) answer3 <- choose(3, 7) print(answer1) print(answer2) print(answer3) Output: 0 0 0 Comment More infoAdvertise with us Next Article Calculate nCr value in R Programming - choose() Function S spp____ Follow Improve Article Tags : R Language R Math-Function Similar Reads Calculate cosine of a value in R Programming - cos() Function cos() function in R Language is used to calculate the cosine value of the numeric value passed to it as argument.

It is defined as: n! = n × (n - 1) × (n - 2) × ... × 2 × 1For example 5! = 5 × 4 × 3 × 2 × 1 = 1200! is defined to be 1.Factorials have important applications in mathematics, co 3 min read Calculating Natural Logarithm of calculated nCr value in R Programming - lchoose() Function lchoose() function in R Language is used to return the natural logarithm of nCr value. This function is equal to log(choose(x)).
