For loop list of tibbles R - r

Question

I want to create a list of random tibbles using a for loop. I have a large data set where I will need to apply functions to lists of tibbles and create lists of tibbles as the outputs. I understand there might be better ways to do this and would also appreciate hearing those but am trying to wrap my head around how for loops work.
I can create a list of random tibbles with each tibble in the list named:
tibble_random1 <- tibble(Number = sample((1:100), 10, replace = TRUE),
Letter = sample((LETTERS), 10, replace = TRUE),
Logical = sample(c("True", "False"), 10, replace = TRUE))
tibble_random2 <- tibble(Number = sample((1:100), 10, replace = TRUE),
Letter = sample((LETTERS), 10, replace = TRUE),
Logical = sample(c("True", "False"), 10, replace = TRUE))
tibble_random3 <- tibble(Number = sample((1:100), 10, replace = TRUE),
Letter = sample((LETTERS), 10, replace = TRUE),
Logical = sample(c("True", "False"), 10, replace = TRUE))
tibble_random <- list(tibble1 = tibble_random1,
tibble2 = tibble_random2,
tibble3 = tibble_random3)
I cannot figure out how to do this with a for loop or if a for loop is completely inappropriate for this.
Thanks.

Initialise a list and fill 1 tibble in every iteration using for loop.
tibble_random <- vector('list', 3)
for(i in seq_along(tibble_random)) {
tibble_random[[i]] <- tibble(Number = sample((1:100), 10, replace = TRUE),
Letter = sample((LETTERS), 10, replace = TRUE),
Logical = sample(c("True", "False"), 10, replace = TRUE))
}
You can also use replicate or lapply to do this without for loop.
tibble_random <- replicate(3, tibble(Number = sample((1:100), 10, replace = TRUE),
Letter = sample((LETTERS), 10, replace = TRUE),
Logical = sample(c("True", "False"), 10, replace = TRUE)), simplify = FALSE)
To assign the names of the list you can use :
names(tibble_random) <- paste0('tibble', seq_along(tibble_random))
