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

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:

# R program to illustrate 
# lfactorial function 
  
# Calling the lfactorial() function 
lfactorial(0) 
lfactorial(1) 
lfactorial(5) 

Output:

[1] 0
[1] 0
[1] 4.787492

Example 2:

# R program to illustrate 
# lfactorial function 
  
# Calling the lfactorial() function 
lfactorial(-4) 

Output:

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