Thanks for this! Question: I have a df with a couple hundred variables. I want to keep all of the variables, but filter out the cases the don’t fall between two specific dates. Do I need to list every variable in the code? In your example, it looks like you’re selecting every variable (FL_DATE, CARRIER, ORIGIN, ORIGIN_CITY_NAME, ORIGIN_STATE_ABR, DEP_DELAY, DEP_TIME, ARR_DELAY, ARR_TIME).
flight %>%
select(FL_DATE, CARRIER, ORIGIN, ORIGIN_CITY_NAME, ORIGIN_STATE_ABR, DEP_DELAY, DEP_TIME, ARR_DELAY, ARR_TIME) %>%
filter(between(FL_DATE, as.Date("2014-01-05"), as.Date("2014-01-10")))
Is there something like a “select all variable” for the date filter for cases?
Thanks!
