Programmatically delete the earlies data files from the data folder

I am trying to delete the earlies (oldest) datasets and keep only 3 of them (the earliest) For example, the viewers by app file, the first 3 datasets are the earlies, as you can see the date attached and the time. The rest 3 of them, are older, and do not want to keep them, good for deletion. The same with log metrics files; the first 3 are the earliest and want to keep them, but the last 3 are the oldest and want to delete them.

Is there a way to programmatically delete, in R, the files I do not need? It would be nice to embed the tidyverse library with this solution.

Here are the code I have written to actually created these data, just so that you are aware of how I have created these.

readr::write_csv(log_metrics,
                     paste0(
                       "data/generated_metrics/log_metrics",
                       format(Sys.time(), "%Y%m%d%H%M"),
                       ".csv"
                     ))
