bike_rides$started_at <- lubridate::ymd_hms(bike_rides$started_at) bike_rides$ended_at <- lubridate::ymd_hms(bike_rides$ended_at)
when I run this code, my df in the environment panel appeared as Tibble(check screenshots). It happened because it is quite a large dataset or? there are more than 3mln rows.
and when I press the play button in the environment panel it does not show me columns and data types anymore.
