Syntax: is.name(x)

Parameters:
x: R object to be tested

Example 1:

# is.name() function 

# Initializing a string 

x <- "sample"

# Calling the is.name() function 
# to check whether the argument is 
# name or not 

is.name(x)

Output:

[1] FALSE

Example 2:

# R program to illustrate 
# is.name() function 

# Coercing the argument to a name
