Once this PR is merged the following code snippet will be valid
``` r
suppressPackageStartupMessages(library(dplyr))
suppressPackageStartupMessages(library(lubridate))
suppressPackageStartupMessages(library(arrow))
df <- tibble(
dates = as.Date(c("2021-04-30", "2021-07-31", "2021-10-31", "2021-01-31"))
)
df %>%
record_batch() %>%
mutate(
semester_without_year = semester(dates),
semester_with_year = semester(dates, with_year = TRUE)) %>%
collect()
#> # A tibble: 4 × 3
#> dates semester_without_year semester_with_year
#> <date> <int> <dbl>
#> 1 2021-04-30 1 2021.1
#> 2 2021-07-31 2 2021.2
#> 3 2021-10-31 2 2021.2
#> 4 2021-01-31 1 2021.1
```
and identical with the `lubridate` result:
``` r
suppressPackageStartupMessages(library(dplyr))
suppressPackageStartupMessages(library(lubridate))
df <- tibble(
dates = as.Date(c("2021-04-30", "2021-07-31", "2021-10-31", "2021-01-31"))
)
df %>%
mutate(
semester_without_year = semester(dates),
semester_with_year = semester(dates, with_year = TRUE))
#> # A tibble: 4 × 3
#> dates semester_without_year semester_with_year
#> <date> <int> <dbl>
#> 1 2021-04-30 1 2021.1
#> 2 2021-07-31 2 2021.2
#> 3 2021-10-31 2 2021.2
#> 4 2021-01-31 1 2021.1
