# states 0.3.1 Unreleased

• Strip readr “spec” attribute from the cowstates and gwstates data. They are both now plain data frames with no attributes. (#22)
• Expand list of short country names in prettyc(), e.g. instead of “Belarus (Byelorussia)”, just “Belarus”.
• Move to testthat 3rd edition (3e).

## Bug fixes

• all.equal() in R 4.1.x (R-devel at this point) will check environments for equivalence as well. This breaks one test since 2e testthat relies on all.equal() for expect_equal(). Moving to testthat 3e fixes this bug. (#26)

# states 0.3.0 2020-12-11

• Although the original COW state list does not distinguish micro-states, like the G&W list does, the cowstates data now has a microstates coding derived from the G&W coding (#24). This makes it easier, for example, to filter out micro-states from a state panel dataset.
• In the gwstates and cowstates data, the “iso3c” columns have been renamed to “gwn” and “cown”, as they are not in fact ISO 3-character country abbreviations (#19).
• plot_missing()’s “space” argument has been renamed “ccode”.
• id_date_sequence() now works with integer years, there is no need to convert them to Date class anymore (#20).

## Improved support for state_panel shortcuts

state_panel() has further improved support for input shortcuts (#3):

• Accepted formats for the “start” and “end” arguments now include 2006, “2006”, “2000-06”, and “2006-06-01”. See parse_date() for details.
• The implied time period is now also inferred from shortcut input when “by” is left at the new default of NULL.
• The “partial” option has gained new “first” and “last” values that also support shortcut input. Previously a shortcut input like 2006 could only be used with the “any” partial option, and to get country-years for states that were independent on the first day of a year one had to use state_panel("YYYY-01-01", partial = "exact", ...). This can now instead be done with state_panel(2006, partial = "first", ...).

## New functions

• Added country_names() to translate country codes to country names and prettyc() to shorten some of the longer country names, like “Macedonia, the former Yugoslav Republic of”.
• Updated vignette on G&W and COW differences to take into account when trying to translate between codes.
• Added compare() helper to compare two statelist data frames prior to merging.
• Added parse_date() to handle more flexible “start” and “end” date input (#12).

## Bug fixes

• fixed a misspelled country name, “Rumania” to “Romania”

# states 0.2.2 2019-01-11

• Added option to use simpler input when generating a yearly panel, i.e. state_panel(2001, 2005) instead of state_panel("2001-01-01", "2005-01-01", by = "year", partial = "any").
• Changed sfind() so that it ignores capitalization and treats character numbers as numbers. These pairs of queries now produce the same results, unlike before:
• “Gabon” and “gabon”,
• 260 and “260”
• Changes in plot_missing() and missing_info():
• make “data” the first argument and “x” the second argument so that it works nicer in pipes.
• add more intelligent defaults so that not all arguments have to be explicitly specified.
• rename the “time_unit” argument to “period”.
• added “partial” argument, it works the same as in state_panel().
• Fixed plot_missing() and missing_info() error when “data” is a tibble (“tbl_df”).

# states 0.2.1 2018-05-04

• plot_missing improvements: examples with Polity data, added a skip_labels option that will plot every n-th label for countries instead of all labels to avoid overplotting on the y-axis. The latter is inspired by https://github.com/xuyiqing/panelView.
• Added Polity combined score as example data set.
• Fixed encoding issue for gwstates\$country_names like Cote d’Ivoire and Wüttemberg.

# states 0.2.0 2018-02-23

• Initial version on CRAN.
• Refactor state_panel and add a partial option to allow including partial state-periods (as opposed to the default which is based on the exact start date, for all period resolutions in “by”).
• Rework plot_missing: fix a bug that would leave out independent states with no cases in the input data; add missing_info function that generates the data underlying the plots.
• Add pkgdown website for states package documentation.

# states 0.1.0 Unreleased

• Initial version on Github.
• Added a NEWS.md file to track changes to the package.
