How to Create a Vector of Zero Length in R

In this article, we are going to discuss how to create a vector of zero length in R programming language.

We can create a vector of zero length by passing the datatype as a value to the vector.

Syntax:

vector=datatype()

There are six data types and each can be used to create a vector of the required datatype. Let’s see how to create a vector of 0 length of each data type.

character()

It is used to create a Numeric vector of 0 length.

Syntax:

vector = character()   

Example: R program to create a numeric vector of 0 length and display

R

# Numeric vector of 0 length
vector < - character()

# display
print(vector)

Output:

character(0)

factor()

It is used to create a Factor vector of 0 length 

Syntax:

vector = factor()   

Example: R program to create a factor vector of length 0 and display

R

# Factor vector of 0 length
vector = factor()

# display
print(vector)

Output:

factor(0)

Levels:

logical()

It is used to create a logical vector of 0 length.

Syntax:

vector = logical()  

Example: R program to create a logical vector  of length 0 and display

R

# logical vector of 0 length
vector = logical()

# display
print(vector)

Output:

logical(0)

integer()

It is used to create an Integer vector of 0 length.

Syntax:

vector = integer ()  

Example: R program to create an integer vector of length 0 and display

R

# Integer vector of 0 length
vector = integer()

# display
print(vector)

Output:

integer(0)

double()

It is used to create a double vector of 0 length.

Syntax:

vector = double()  

Example: R program to create a double vector of 0 length and display

R

# double vector of 0 length
vector = double()

# display
print(vector)

Output:

numeric(0)

raw()

It is used to create a raw vector of 0 length.

Syntax:

vector = raw()  

Example: R program to create a Raw vector of length 0 and display

R

# raw vector of 0 length
vector = raw()

# display
print(vector)

Output:

raw(0)

complex()

It is used to create a complex vector of 0 length.

Syntax:

vector = complex()  

Example: R program to create a complex vector of 0 length and display

R

# complex vector of 0 length
vector = complex()

# display
print(vector)

Output:

complex(0)
