How to get Item in a Vector at a Specific Index in R ?

Answer

To get an item in a vector at a specific index in R, you can use indexing with square brackets.

✐ Examples

1 Access Item at Specific Index

In this example,

We create a vector named myVector containing elements.
We access an item at a specific index in the vector using square brackets [ ] and specify the index of the item we want to access.
The item at the specified index is returned.
We print the accessed item to the console.

R Program

# Create a vector
myVector <- c("apple", "banana", "cherry", "date")

# Access item at index 2
accessedItem <- myVector[2]

# Print accessed item
print(accessedItem)

Output

[1] "banana"

2 Access Multiple Items by Indices

In this example,

We create a vector named myVector containing elements.
We use a vector of indices to specify multiple indices of items we want to access.
We access multiple items at specified indices using square brackets [ ] and the vector of indices.
The items at the specified indices are returned in the same order as the indices vector.
We print the accessed items to the console.

R Program

# Create a vector
myVector <- c("apple", "banana", "cherry", "date")

# Access multiple items by indices
indices <- c(1, 3)
accessedItems <- myVector[indices]

# Print accessed items
print(accessedItems)

Output

[1] "apple"  "cherry"
