Is there anyway to stop my loop from being interrupted by the rate limit? I would like my code to wait to execute until the time limit has passed if possible.

    I was able to resolve it by wrapping get_timeline() function in the following code. The function get_timeline_unlimited calls itself recursively after waiting the required time for the rate limit to reset. So far it worked well for me with no issues.

     get_timeline_unlimited <- function(users, n){
    
      if (length(users) ==0){
        return(NULL)
      }
    
      rl <- rate_limit(query = "get_timeline")
    
      if (length(users) <= rl$remaining){
        print(glue("Getting data for {length(users)} users"))
        tweets <- get_timeline(users, n, check = FALSE)  
      }else{
    
        if (rl$remaining > 0){
          users_first <- users[1:rl$remaining]
          users_rest <- users[-(1:rl$remaining)]
          print(glue("Getting data for {length(users_first)} users"))
          tweets_first <- get_timeline(users_first, n, check = FALSE)
          rl <- rate_limit(query = "get_timeline")
        }else{
          tweets_first <- NULL
          users_rest <- users
        }
        wait <- rl$reset + 0.1
        print(glue("Waiting for {round(wait,2)} minutes"))
        Sys.sleep(wait * 60)
    
        tweets_rest <- get_timeline_unlimited(users_rest, n)  
        tweets <- bind_rows(tweets_first, tweets_rest)
      }
      return(tweets)
    }
