Check if Object is of the Character Data type in R Programming – is.character() Function

is.character() Function in R Language is used to check if the object is of the form of a string/character or not. It will return true if any element of the object is of the character data type.

Syntax: is.character(Object)

Parameter:
Object: It could be an array, list, vector, etc.

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
