- The scale functions (e.g.
scale_x_grates_isoweek()) gain a
breaksargument to allow exact specification of breaks.
CRAN release: 2023-03-17
For the first major release of grates a significant refactor has been undertaken that builds upon lessons learnt over the last two years. Whilst we have tried to limit breaking changes some functionality has been removed and some function parameters altered (see details below):
<grates_month>objects are now always stored relative to the UNIX epoch. This is equivalent to setting
origin = 0in the previous release. Calling the function with an
originargument will now error.
Trying to create a
nset to 1 will now error. Uses are encouraged to use
<grates_yearmonth>for this case.
<grates_int_period>is now a defunct as it did not fit with the scope of the package (i.e grouped dates, not grouped integers). In particular the
is_int_period()will now error on use.
as_yearweek()no longer parsers character strings of the form “YYYY-Www” (e.g. “2020-W01”).
epiweek()now allow construction of grates objects directly from year and week integer vectors.
yearquarter()constructors have been similarly changed to allow construction from year and month/quarter integer vectors.
The old incarnation of direct constructors now begin with a
new_epiweek(), …). This is to distinguish them from more user friendly constructors that we have introduced (see above).
<grates_yearmonth>) and associated functions have been introduced. This object is similar to what was previously obtained via a call of
month(x, n = 1L, origin = 0L)(now defunct - see above).
<grates_epiweek>respectively) and associated functions. Internally these are similar to the corresponding
<grates_yearweek>objects but with a marginally more efficient implementation.
is.numeric()methods for grates objects previously returned FALSE. Calls to these methods now dispatch to the default implementation based on the underlying type and should now return TRUE.
CRAN release: 2021-10-21
seq()methods now implemented for all grates objects.
CRAN release: 2021-05-28
This is a breaking release that changes the underlying implementations of the different grate constructors and associated scales for ggplot2. There has also been some renaming of function arguments to bring greater consistency across packages.
We now make more use of the high level API introduced by the clock package for working with R’s date and date-time types.
