I want to convert yyyy-mm-dd hh-mm-ss to yyyy-mm-dd. So I type the code showed below.
tripdata_v1 <- format(tripdata_v1$started_at, format = "%Y-%m-%d")
And then tripdata_v1 appear in value section instead of data section.(top right pane)
How can I change the time frame and remain tripdata_v1 in data section.
