| mydate1 = as.Date("2000-01-01") | |

| # EASY: sequence with every other int | |
| seq(1, 60, by=2) | |
| # HARD: sequence with every other day | |
| seq(mydate1, mydate2, by=???) # day? | |
| # pretend you're new to R | |
| # you don't know about lubridate or POSIX | |
| # try to discover the answer as though you're naive | |
| # start from ?seq and google searches | |
| # HARDER: sequence sampled at 2x per day (every 12 hours) | |
| seq(mydate1, mydate2, ???) | |
| # HINT: things that don't work: | |
| seq(mydate1, mydate2, days(2)) | |
| seq(mydate1, mydate2, hours(12)) | |
| seq(mydate1, mydate2, by=0.5) | |
