These three functions are responsible for –
The role of is.atomic is to test if the vector is atomic in nature.
Is.numeric checks if the object has an integer or a double type and does not belong to “factor”,
“Data”, “POSIXt” or “difftime” class.
is.vector() is responsible for testing if the object is vector and therefore, has no attributes
excluding names.
