How to create a Vector of Empty Vectors in R - Step by Step Examples

How to create a Vector of Empty Vectors in R ?

To create a vector of empty vectors in R, you can initialize an empty list and populate it with empty vectors using the replicate function.

In this example,

We create an empty list named empty_vector_list.
We use the replicate function to add empty vectors to the list.
Inside the replicate function, we specify the number of empty vectors to replicate.
The list empty_vector_list now contains the desired number of empty vectors.

empty_vector_list <- list()
num_empty_vectors <- 5
empty_vector_list <- replicate(num_empty_vectors, vector())
print(empty_vector_list)

[[1]]
character(0)

[[2]]
character(0)

[[3]]
character(0)

[[4]]
character(0)

[[5]]
character(0)

In this example,

We create an empty list named empty_vector_list.
We use a for loop to iterate a specific number of times (e.g., 5 times).
Within each iteration, we add an empty vector to the list using the vector() function.
The list empty_vector_list now contains the desired number of empty vectors.

empty_vector_list <- list()
num_empty_vectors <- 5
for (i in 1:num_empty_vectors) {
  empty_vector_list[[i]] <- vector()
}
print(empty_vector_list)

[[1]]
character(0)

[[2]]
character(0)

[[3]]
character(0)

[[4]]
character(0)

[[5]]
character(0)
