If you are working with imaginary components, you might want to find whether you are working with complex numbers or not and that’s where the is.complex() function helps you.
The is.complex() is a built-in R function that checks whether an input object is of type “complex”. It returns TRUE if it is complex and FALSE if not.
Syntax
is.complex(obj)
Parameters
| Name | Value |
| obj | It is an input R object that will be checked for data type “complex”. |
Visual Representation
Check if an input object is complex
R does not implicitly convert any number to a complex number; you have to create a complex number using the complex() function and pass the “real” and “imaginary” arguments.
is.complex(1 + 9i) # TRUE
is.complex(21) # FALSE
is.complex(2 - 1i) # TRUE
data <- complex(real = 1, imaginary = 2)
is.complex(data) # TRUELogical values
The is.complex() function returns FALSE for logical (TRUE or FALSE) values.
bool_val <- TRUE
is.complex(bool_val) # FALSE
bool_value <- FALSE
is.complex(bool_value) # FALSECharacter strings
The is.complex() function returns FALSE for character vectors.
str <- "Willow!"
is.complex(str) # FALSE
et <- ""
is.complex(et) # FALSE
That’s all!
