Calculate Arithmetic mean in R Programming – mean() Function

function in R Language is used to calculate the arithmetic mean of the elements of the numeric vector passed to it as argument. **mean()**

Syntax:mean(x, na.rm)

Parameters:

x:Numeric Vector

na.rm:Boolean value to ignore NA value

**Example 1:**

`# R program to calculate ` `# Arithmetic mean of a vector ` ` ` `# Creating a numeric vector ` `x1 <` `-` `c(` `1` `, ` `2` `, ` `3` `, ` `4` `, ` `5` `, ` `6` `) ` `x2 <` `-` `c(` `1.2` `, ` `2.3` `, ` `3.4` `, ` `4.5` `) ` `x3 <` `-` `c(` `-` `1` `, ` `-` `2` `, ` `-` `3` `, ` `-` `4` `, ` `-` `5` `, ` `-` `6` `) ` ` ` `# Calling mean() function ` `mean(x1) ` `mean(x2) ` `mean(x3) ` |

**Example 2:**

`# R program to calculate ` `# Arithmetic mean of a vector ` ` ` `# Creating a numeric vector ` `x1 <` `-` `c(` `1` `, ` `2` `, ` `3` `, NA, ` `5` `, NA, NA) ` ` ` `# Calling mean() function ` `# including NA values ` `mean(x1, na.rm ` `=` `FALSE) ` ` ` `# Calling mean() function ` `# excluding NA values ` `mean(x1, na.rm ` `=` `TRUE) ` |
