Calculate nCr value in R Programming – choose() Function
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 combinationsReturns: The number of r combinations from a total of n elements, i.e, nCr value.
Example 1:
# 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.
# 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) |

filter_none
Output:
