library(actuaryr)Retrieve the date in reference to the base date.
Build a function using dref_ + first letters of the reference day.
| of month | of quarter | of year | |
|---|---|---|---|
| first day | dref_fdom() |
dref_fdoq() |
dref_fdoy() |
| first working day | dref_fwdom() |
dref_fwdoq() |
dref_fwdoy() |
| last day | dref_ldom() |
dref_ldoq() |
dref_ldoy() |
| last working day | dref_lwdom() |
dref_lwdoq() |
dref_lwdoy() |
Examples:
dref_fdom("2019-09-21")
#> [1] "2019-09-01"
dref_fwdoq("2019-09-21")
#> [1] "2019-07-01"
dref_ldoy("2019-09-21")
#> [1] "2019-12-31"
dref_lwdom("2019-09-21")
#> [1] "2019-09-30"Compare two tables with compare().
x <- data.frame(
v1 = 1:3,
v2 = 4:6
)
y <- data.frame(
v1 = 1:3,
v2 = 7:9
)
compare(x, y)
