In this article, we will discuss how to append values to a vector using a loop in R Programming Language.
Appending values to an empty vector
Here we are going to append the values using for loop to the empty vector.
Syntax:
for(iterator in range) {
vector = c(vector, iterator)
}where,
- range is the range of values
- iterator is to iterate the range of values
- c(vector,iterator) is an append function which will append values to the vector
Example:
R
# create empty vector vector1 = c()
# display print(vector1)
# use for loop to add elements from 1 to 5 for(i in 1: 5) {
vector1 = c(vector1, i)
} # display vector1 |
Output:
NULL [1] 1 2 3 4 5
Perform Operation and Append Values to Vector
Here we are going to perform some numeric operations and append values to the empty vector. We can perform cube operation and append to empty vector.
Syntax:
for(iterator in range) {
vector = c(vector, operation(iterator))
}where,
- range is the range of values
- iterator is to iterate the range of values
- c(vector,operation(iterator) ) is an append function which will append values to the vector by performing some operation
Here we are going to append the cube values to the vector
Example:
R
# create empty vector vector1 = c()
# display print(vector1)
# use for loop to add elements from # 1 to 5 with cube values for(i in 1: 5) {
vector1 = c(vector1, i*i*i)
} # display vector1 |
Output:
NULL [1] 1 8 27 64 125
Append a Single Value to Vector
Here we are going to append a value for an existing vector.
Syntax:
c(existing_vector,new)
where,
- existing_vector is the vector
- new is the values to be appended
Example:
R
# create vector vector1 = c(1, 2, 3, 4, 5)
# display print(vector1)
# append 34 vector1 = c(vector1, 34)
# display vector1 |
Output:
[1] 1 2 3 4 5 [1] 1 2 3 4 5 34
Append Multiple Values to Existing Vector
Here we are going to append multiple values to the existing vector using for loop.
Syntax:
for(iterator in range) {
vector = c(existing_vector, iterator)
}where,
- range is the range of values
- iterator is to iterate the range of values
- c(existing_vector,iterator) is an append function which will append values to the existing vector
Example:
R
# create vector vector1 = c(6, 7, 8, 9, 10)
# display print(vector1)
# use for loop to add elements from 1 to 5 for(i in 1: 5) {
vector1 = c(vector1, i)
} # display vector1 |
Output:
[1] 6 7 8 9 10 [1] 6 7 8 9 10 1 2 3 4 5
