# Check if values in a vector are True or not in R Programming – all() and any() Function

** all()** function in R Language will check in a vector whether all the values are true or not.

Syntax:all(x, na.rm)

Parameters:x:vectorna.rm:logical, if NA value to removed before result

**Example 1:**

`# R program to illustrate` `# all function` ` ` `# Example vector` `<x1 <` `-` `c(` `1` `, ` `2` `, ` `3` `, ` `-` `4` `, ` `5` `) ` ` ` `all` `(x1 < ` `0` `) ` |

**Output:**

FALSE

Here in the above code, we have created an example vector and applied `all()`

function on it.

Clearly all the values are not less than zero, one value -4 is less than zero, so the answer is FALSE.

**Example 2: Using na.rm argument**

`# R program to illustrate` `# all function with na.rm` ` ` `# Example vector with NA value` `x2 <` `-` `c(` `1` `, ` `2` `, ` `3` `, ` `-` `4` `, ` `5` `, NA) ` ` ` `# Apply all function with na.rm = TRUE` `all` `(x2 < ` `-` `10` `, na.rm ` `=` `TRUE) ` ` ` |

**Output:**

TRUE

Here in the above code, we set the value of na.rm to TRUE. So the output is TRUE. As all of them are greater than -10 in the above code.

#### any() Function

**any()** function will check in vector whether any of the value is true.

Syntax:any(x, na.rm)

Parameters:x:vectorna.rm:logical, if NA value to removed before result

**Example 1: any() function**

`# R program to illustrate` `# any() function` ` ` `# Example vector` `x1 <` `-` `c(` `1` `, ` `2` `, ` `3` `, ` `-` `4` `, ` `5` `, ) ` ` ` `# Apply any function in R` `any` `(x1 < ` `0` `) ` |

**Output:**

TRUE

Here in the above code, we have applied `any()`

function. Since one value is “-4” (lesser than 0), so the answer is TRUE.

**Example 2: Any function using na.rn argument**

`# R program to illustrate` `# any function with na.rm` ` ` `# Example vector with NA value` `x2 <` `-` `c(` `1` `, ` `2` `, ` `3` `, ` `-` `4` `, ` `5` `, NA) ` ` ` `# Apply any function with na.rm = TRUE` `any` `(x2 < ` `-` `10` `, na.rm ` `=` `TRUE) ` |

**output:**

FALSE

Here in the above code, we set the value of na.rm to TRUE. So the output is False. As all of them are lesser than -10 in the above code.
