I mainly use this for\nmerging different data sources:\n\n1. Create a master template that reflects one of the independent states\n lists.\n2. For each data source, normalize to a copy of the master template.\n Doing this by source makes it easier to identify and address issues\n like missing values or observation for non-independent states.\n3. In the end, merge everything together. Since all the inputs are\n already normalized to a proper state panel list, there should be no\n issues.\n\nWhat the package does:\n\n- It contains the Gleditsch and Ward (G&W) as well as the Correlates of\n War (COW) state system membership lists.\n\n``` r\nlibrary(\"states\")\n \ndata(gwstates)\ndata(cowstates)\n```\n\n- Search them with `sfind`, this can be helpful for manual coding:\n\n``` r\nsfind(260)[, 1:6]\n#> list ccode code3c country_name start end\n#> 45 GW 260 GFR German Federal Republic 1949-09-21 9999-12-31\n#> 299 COW 260 GFR German Federal Republic 1955-05-05 1990-10-02\nsfind(\"German\")[, 1:6]\n#> list ccode code3c country_name start end\n#> 44 GW 255 GMY Germany (Prussia) 1816-01-01 1945-05-07\n#> 45 GW 260 GFR German Federal Republic 1949-09-21 9999-12-31\n#> 46 GW 265 GDR German Democratic Republic 1949-10-05 1990-10-02\n#> 297 COW 255 GMY Germany 1816-01-01 1945-05-08\n#> 298 COW 255 GMY Germany 1990-10-03 9999-12-31\n#> 299 COW 260 GFR German Federal Republic 1955-05-05 1990-10-02\n#> 300 COW 265 GDR German Democratic Republic 1954-03-25 1990-10-02\n```\n\n- You can use it to build a country-year template that matches either\n the COW or G&W state lists.\n\n``` r\ncountries <- state_panel(1991, 2001)\n \nstr(countries)\n#> 'data.frame': 2091 obs. of 2 variables:\n#> $ gwcode: int 2 2 2 2 2 2 2 2 2 2 ...\n#> $ year : int 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 ...\n```\n\n- Visualize missing/non-independent cases in your data. See this related\n [blog post for more\n details](https://www.andybeger.com/blog/2016-09-13-data-management/).\n\n``` r\ndata(\"polity\")\nstr(polity)\n#> 'data.frame': 17228 obs. of 3 variables:\n#> $ ccode : num 700 700 700 700 700 700 700 700 700 700 ...\n#> $ year : num 1800 1801 1802 1803 1804 ...\n#> $ polity: num -6 -6 -6 -6 -6 -6 -6 -6 -6 -6 ...\n \nplot_missing(polity, x = \"polity\", ccode = \"ccode\", statelist = \"COW\")\n```\n\n

\n\nFor the underlying data (missing info requires date input):\n\n``` r\npolity$date <- as.Date(paste0(polity$year, \"-01-01\"))\nmm <- missing_info(polity, x = \"polity\", ccode = \"ccode\", \n time = \"date\", period = \"year\",\n statelist = \"COW\")\nhead(mm)\n#> ccode date independent missing_value status\n#> 18671 2 1800-01-01 0 FALSE Complete, non-independent\n#> 18672 2 1801-01-01 0 FALSE Complete, non-independent\n#> 18673 2 1802-01-01 0 FALSE Complete, non-independent\n#> 18674 2 1803-01-01 0 FALSE Complete, non-independent\n#> 18675 2 1804-01-01 0 FALSE Complete, non-independent\n#> 18676 2 1805-01-01 0 FALSE Complete, non-independent\n```\n\n## Install\n\nThe package is on CRAN and can be installed with:\n\n``` r\ninstall.packages(\"states\")\n```\n\nOr to install from GitHub:\n\n``` r\nlibrary(\"remotes\")\nremotes::install_github(\"andybega/states\")\n```\n\n## Citations\n\nFor the [Gleditsch and Ward (G&W) state\ndata](http://ksgleditsch.com/statelist.html):\n\nGleditsch, Kristian S. & Michael D.
