I want to take a sample of 400 out of a data frame with 2000 rows, the way to do that is simply

s1 <- sample_n(t, 400) 

Now I want to do that 10000 times. I guess boot() is the function to use here to avoid an overload but I don't know what I need to write as the function part to get what I want

boot(t, ?, 10000)

Can anyone more experienced with r help me out here?

CodePudding user response：

You can also replicate the random sample using sample_n like this:

library(dplyr)
bind_rows(replicate(10, df %>% sample_n(400), simplify = F)) 

Please note: change the 10 to 10000 for 10000 times.

Random data

df <- data.frame(v1 = runif(2000, 0, 1))
