Compute the Natural Logarithm of Factorial in R Programming - lfactorial() Function

Last Updated : 10 Jun, 2020

lfactorial() function in R Language is used to compute the natural logarithm of factorial of x i.e, ln(x!).

Syntax: lfactorial(x) Parameters: x: positive numeric value

Example 1:

Python3

# R program to illustrate
# lfactorial function

# Calling the lfactorial() function
lfactorial(0)
lfactorial(1)
lfactorial(5)

Output:

[1] 0
[1] 0

# lfactorial function

# Calling the lfactorial() function
lfactorial(-4)

Output:

[1] Inf
Warning message:
In lfactorial(-4) : value out of range in 'lgamma'
