# Suppress Warnings Globally in R

• Last Updated : 31 Aug, 2021

In this article, we are going to discuss how to suppress warnings globally in R programming language.

A warning is a message that does not disturb the program flow but displays the warning along with the output. In order to suppress the warnings globally, we have to set warn=-1 in the options function

Syntax:

options(warn = – 1)

If you want to see the warnings then set warn=0

Example: R program to see the warning when using pmax and pmin

## R

 `# pmax function and display the warnings``# pmax function will return the parallel``# maximum of two vectors``pmax``(``c``(1, 2, 3), ``c``(1, 2, 3, 4, 5))`` ` `# pmin function and display the warnings``# pmin function will return the parallel``# minimum of two vectors``pmin``(``c``(1, 2, 3), ``c``(1, 2, 3, 4, 5))`

Output:

Example: R program to suppress the warning messages when using pmax and pmin

## R

 `# suppress the warnings by setting warn=-1``options``(warn=-1)`` ` `# pmax function and display the warnings``# pmax function will return the parallel``# maximum of two vectors``pmax``(``c``(1, 2, 3), ``c``(1, 2, 3, 4, 5))`` ` `# pmin function and display the warnings``# pmin function will return the parallel``# minimum of two vectors``pmin``(``c``(1, 2, 3), ``c``(1, 2, 3, 4, 5))`

Output:

```12345
12312```

If we want to see the warnings again, set warn=0

Example: R program to again see the warnings

## R

 `# display the warnings by setting warn=0``options``(warn=0)`` ` `# pmax function and display the warnings``# pmax function will return the parallel``# maximum of two vectors``pmax``(``c``(1, 2, 3), ``c``(1, 2, 3, 4, 5))`` ` `# pmin function and display the warnings``# pmin function will return the parallel``# minimum of two vectors``pmin``(``c``(1, 2, 3), ``c``(1, 2, 3, 4, 5))`

Output:
