R doesn't provide us with a built in delete or remove function, but removing items from a list is pretty simple. We can also use multiple indexing to remove multiple elemets. In this article, we will see how to remove an element from a list in R.
The first way we can remove items from a list is with the position index. To remove elements, we set the value to
lst = list(1, 2, 3) lst[] = NULL # remove the first element
We can also remove multiple elements with a vector of positions.
lst = list(1, 2, 3) lst[c(1, 3)] = NULL # removes the first and third element
Next, we can also remove lists using the names or keys of the values and setting the values to null.
group = list(count = 3, name = "test", details = c(1, 2, 3)) group[["count"]] = NULL
Again, we can also remove multiple elements using a vector and setting all values to NULL.
group = list(count = 3, name = "test", details = c(1, 2, 3)) group[c("count", "details")] = NULL
