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
  • 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 file to track changes to the package.
