How to Remove Specific Item from a Vector in R - Step by Step Examples

How to Remove Specific Item from a Vector in R ?

To remove a specific item from a vector in R, you can use logical indexing or the setdiff function.

In this example,

We start by creating a vector named vec with some integer values.
We specify the item we want to remove and store it in a variable named item_to_remove.
We use logical indexing to create a logical vector that is TRUE for all elements not equal to item_to_remove and FALSE otherwise.
We use this logical vector to subset the original vector, effectively removing the specified item.
Finally, we print the new vector to see the result.

vec <- c(10, 20, 30, 40, 50)
item_to_remove <- 30
vec_new <- vec[vec != item_to_remove]
print(vec_new)

In this example,

We start by creating a vector named vec with some integer values.
We specify the item we want to remove and store it in a variable named item_to_remove.
We use the setdiff function to remove the specified item. The setdiff function returns the difference between the original vector and a vector containing the item to remove.
We create a new vector vec_new that includes all elements of vec except the one specified in item_to_remove.
Finally, we print the new vector to see the result.

vec <- c(10, 20, 30, 40, 50)
item_to_remove <- 30
vec_new <- setdiff(vec, item_to_remove)
print(vec_new)
