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
# 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
# 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
# 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:
