# Get the natural logarithm of the beta value of Non-Negative numeric vectors in R Language – lbeta() Function

** 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
