aweek 1.0.1

CRAN MAINTENANCE

• as.POSIXlt() now converts NULL to an empty POSIXlt object, so a test that was previously checking for an error failed. That test has been fixed (#33, @zkamvar)

aweek 1.0.0

NEW FUNCTIONS

• change_week_start() allows the user to change the week_start attribute of an aweek object, adjusting the weeks to match the new attribute accordingly.
• get_aweek() can generate aweek objects from a vector of week numbers. It has the ability to take into account different week start times.
• get_date() is similar to get_aweek(), but returns dates instead.
• as.aweek() allows users to create aweek object directly from characters with validation. It also allows for dates by passing to date2week().
• as.data.frame.aweek() is a new function that allows aweek objects to be directly incorporated into data frames.
• as.list.aweek() will now preserve the aweek structure in lists
• trunc.aweek() will truncate the day to the first day of the week.
• rep.aweek() allows repeating aweek characters.
• factor_aweek() allows the user to create aggregated aweek objects on the fly.

BREAKING CHANGES

There are a couple of breaking changes coming to aweek that will improve stability by removing unclear coercion methods (see https://github.com/reconhub/aweek/issues/20).

• It is no longer possible to combine aweek objects if they do not share the same week_start attribute. This will result in an error informing the user to adjust the week_start attribute with the change_week_start() function.
• Factors will no longer coerce factors when combining aweek objects.
• Using date2week() with factor = TRUE and floor_day = FALSE now throws an error instead of a warning (as prophesized in #13).

DOCUMENTATION

• The vignette has been updated to include an explanation of the underlying week calculation from date.
• The aweek class documentation has been updated to detail the different elements of the object and the calculations.
• Package documentation package?aweek has been added for an introduction.

BUG FIX

• conversions will now retain the names of the object.

MISC

• More checks that weekdays and weeks are within the correct bounds have been added.
• as.Date.aweek has been simplified to no longer rely on regex since the aweek class is standard.
• The internal get_wday() has been vastly simplified with improved speed.

aweek 0.3.0

• The week_start argument now defaults to the global option aweek.week_start, which will be a number from 1 to 7, representing the days of the week in the ISO 8601 standard.
• set_week_start() is a convenience allowing the user to set the default aweek.week_start option via integer or character input.
• get_week_start() is a wrapper for getOption("aweek.week_start", 1L) and attr(w, "week_start") for aweek objects.

aweek 0.2.2

• Simplified conversion to factors.
• Using factor = TRUE without floor_day = TRUE will now issue a message indicating that this is deprecated in future versions of aweek (see #13).

aweek 0.2.1

• Fix bug where NAs threw errors in the dates (found: @aspina7, #12)

• as.data.frame.aweek() will now convert aweek objects to columns of data frames without losing class or attributes

• The introduction vignette has been updated to reflect this change.

aweek 0.2.0

• Subsetting and concatenating methods added to the aweek class (see #1)
• Documentation divided into smaller chunks
• as.POSIXlt() bug where tz was not being passed was fixed.
• date2week(): an error is now issued if users specify non-ISO 8601 dates OR don’t specify a format option. (found: @scottyaz, #2)
• Best practices added to vignette
• Fix test that would fail every seven days on CRAN

aweek 0.1.0

• First official release of aweek on CRAN

aweek 0.0.5.9000

• date2week() and week2date() can now take days represented as characters in the current or English locale.

aweek 0.0.4.9000

• date2week() gains a factor argument, which will automatically compute the levels within the date range.

aweek 0.0.3.9000

• date2week() now properly accounts for dates in December that occur in the first week of the next year.

aweek 0.0.2.9000

• floor_day now truncates the week instead changing the last digit to 1 for aesthetics. (Thanks to @aspina7 for the suggestion) q print.aweek() now displays the day of the week in the current locale.

aweek 0.0.1.9000

• First version of package
• date2week() converts dates to aweek objects
• week2date() converts aweek objects or character strings to dates
• as.Date() does the same thing as above
• as.POSIXlt() as well
• as.character() will unclass the aweek object
• Added a NEWS.md file to track changes to the package.
