lbeta() function in R Language is used to return the natural logarithm of the beta function. The beta function is also known as Euler’s integral of the first kind.

Syntax: lbeta(a, b)

Parameters:
a, b: non-negative numeric vectors

Example 1:




# R program to illustrate
# lbeta function
  
# Calling the lbeta() function
lbeta(1, 2)
lbeta(2, 2)
lbeta(3, 5)

Output:

[1] -0.6931472
[1] -1.791759
[1] -4.65396

Example 2:




# R program to illustrate
# lbeta function
  
# Initializing some vectors
x <- c(1, 2, 3)
y <- c(2, 4, 6)
  
# Calling the lbeta() function
lbeta(x, y)

Output:

[1] -0.6931472 -2.9957323 -5.1239640
