How to create a List of size N in R


How to create a List of size N in R ?

Answer

To create a list of size N in R, you can use the rep function or the vector function.



✐ Examples

1 Create a List of Size N with Default Values Using rep Function

In this example,

  1. We use the rep function to create a list of size N with each element initialized to a default value.
  2. The rep function repeats the default value N times, creating a list of that size.
  3. Finally, we print the created list to standard output.

R Program

size <- 5
default_value <- 0
list_rep <- rep(default_value, size)
cat('List of size', size, 'with default values:', list_rep, '\n')

Output

List of size 5 with default values: 0 0 0 0 0

2 Create a List of Size N with Default Values Using vector Function

In this example,

  1. We use the vector function to create a list of size N with each element initialized to a default value.
  2. The vector function initializes a list of the specified type and length, filled with default values.
  3. Finally, we print the created list to standard output.

R Program

size <- 5
default_value <- 0
list_vector <- vector(mode = 'numeric', length = size)
list_vector <- rep(default_value, size)
cat('List of size', size, 'with default values:', list_vector, '\n')

Output

List of size 5 with default values: 0 0 0 0 0

Summary

In this tutorial, we learned How to create a List of size N in R language with well detailed examples.
