Example 1:
# R Program to illustrate # the use of is.character function # Creating a vector of mixed datatype x1 < - c( "Hello" , "Geeks" , 100 )
# Creating a vector of Numeric datatype x2 < - c( 10 , 20 , 30 )
# Calling is.character() function is .character(x1)
is .character(x2)
|
Output:
[1] TRUE [1] FALSE
Example 2:
# R Program to illustrate # the use of is.character function # Create the vectors with different length vector1 < - c( 1 , 2 , 3 )
vector2 < - c( "GFG" , "Geeks" , "Hello" )
# taking this vector as input result < - array(c(vector1, vector2), dim = c( 3 , 3 , 2 ))
# Calling is.character() function is .character(result)
|
Output:
[1] TRUE
