ndi v0.2.0

New Features

New Functions

  • Added duncan_cuzzort() function to compute the aspatial racial or ethnic Absolute Centralization (ACE) based on Duncan, Cuzzort, & Duncan (1961; LC:60007089) and Massey & Denton (1988)
  • Added hoover() function to compute the aspatial racial or ethnic Delta (DEL) based on Hoover (1941) and Duncan, Cuzzort, & Duncan (1961; LC:60007089)
  • Added james_taeuber() function to compute the aspatial racial or ethnic Dissimilarity Index (D) based on James & Taeuber (1985)
  • Added lieberson() function to compute the aspatial racial or ethnic Isolation Index (xPx*) based on Lieberson (1981; ISBN-13:978-1-032-53884-6) and and Bell (1954)
  • Added theil() function the aspatial racial or ethnic Entropy (H) based on Theil (1972; ISBN:978-0-444-10378-9) and Theil & Finizza (1971)
  • Added white_blau() function to compute an index of spatial proximity (SP) based on White (1986) and Blau (1977; ISBN-13:978-0-029-03660-0)
  • Thank you for the feature suggestions above, Symielle Gaston
  • Added denton() function to compute the aspatial racial or ethnic Relative Clustering (RCL) based on Massey & Denton (1988)
  • Added denton_cuzzort() function to compute the aspatial racial or ethnic Relative Concentration (RCO) based on Massey & Denton (1988) and Duncan, Cuzzort, & Duncan (1961; LC:60007089)
  • Added duncan_duncan() function to compute the aspatial racial or ethnic Relative Centralization (RCE) based on Duncan & Duncan (1955b) and Massey & Denton (1988)
  • Added massey() function to compute the aspatial racial or ethnic Absolute Clustering (ACL) based on Massey & Denton (1988)
  • Added massey_duncan() function to compute the aspatial racial or ethnic Absolute Concentration (ACO) based on Massey & Denton (1988) and Duncan, Cuzzort, & Duncan (1961; LC:60007089)
  • Added morgan_denton() function to compute the aspatial racial or ethnic Distance-Decay Interaction Index (DPxy*) based on Morgan (1983) and Massey & Denton (1988)
  • Added morgan_massey() function to compute the aspatial racial or ethnic Distance-Decay Isolation Index (DPxx*) based on Morgan (1983) and Massey & Denton (1988)

New Function Capabilities

  • Added geo_large = 'place' for census-designated places, geo_large = 'cbsa' for core-based statistical areas, geo_large = 'csa' for combined statistical areas, and geo_large = 'metro' for metropolitan divisions as the larger geographical unit in atkinson(), bell(), bemanian_beyer(), denton(), denton_cuzzort(), duncan(), duncan_cuzzort(), duncan_duncan(), hoover(), james_taeuber(), lieberson(), massey(), massey_duncan(), morgan_denton(), morgan_denton(), morgan_massey(), sudano(), theil(), and white(), white_blau() functions.
  • Added census block group computation for anthopolos() by specifying geo == 'cbg' or geo == 'block group'
  • Added holder argument to atkinson() function to toggle the computation with or without the Hölder mean. The function can now compute A without the Hölder mean. The default is holder = FALSE.
  • Added crs argument to anthopolos(), bravo(), and white_blau() functions to provide spatial projection of the distance-based metrics
  • The gini() function now computes the aspatial racial or ethnic Gini Index (G) based on Gini (1921) as the main outcome. Arguments geo_large, geo_small, subgroup, and omit_NAs were added and argument geo was deprecated. The gini() function still retrieves the original output of the aspatial income Gini Index (G) at each smaller geography and is moved from the g output to g_data output.
  • Specifying census block groups in geo or geo_small arguments is now 'block group' or 'cbg' to match internal get_acs() function from the tidycensus package

Updates

Bug Fixes

  • Fixed NOTE in CRAN checks to provide package anchors for Rd \link{} targets not in the package itself and the base packages within 'ndi-package.Rd'
  • Updated population-weighted quantile method from stats::quantile to Hmisc::wtd.quantile in powell_wiley() thanks to a contribution (#32) by Hunter Miller
  • bell() function computes the Interaction Index (Bell) not the Isolation Index as previously documented. Updated documentation throughout.
  • Fixed bug in bell(), bemanian_beyer(), duncan(), sudano(), and white() functions when a smaller geography contains n=0 total population, will assign a value of zero (0) in the internal calculation instead of NA
  • Fixed bug in atkinson() function to properly compute the income Atkinson Index
  • Renamed AI as A, DI as D, Gini as G, and II as xPy* to align with the definitions from Massey & Denton (1988). The output for atkinson() now produces a instead of ai. The output for duncan() now produces d instead of ai. The output for gini() now produces g instead of gini. The output for bell() now produces xPy_star instead of II. The internal functions ai_fun(), di_fun() and ii_fun() were renamed a_fun(), ddd_fun() and xpy_star_fun(), respectively.
  • 'package.R' deprecated. Replaced with 'ndi-package.R'
  • Output of racial or ethnic residential segregation indices is now rounded to four significant digits

New Dependencies

  • Hmisc, tigris, and units are now Imports

Updated Documentation

  • Split up vignette into three separate vignettes: 'ndi1', 'ndi2', and 'ndi3' for the NDI, racial or ethnic residential segregation, and additional socioeconomic disparity indices, respectively
  • Consolidated DESCRIPTION
  • Reformatted functions for consistent internal structure
  • Re-formatted code and documentation throughout for consistent readability
  • Renamed 'race/ethnicity' or 'racial/ethnic' to 'race or ethnicity' or 'racial or ethnic' throughout documentation to use more modern, inclusive, and appropriate language
  • Updated documentation about value range of V (White) from {0 to 1} to {-Inf to Inf}
  • Added examples for atkinson(), duncan_cuzzort(), duncan_duncan(), gini(), hoover(), james_taeuber(), lieberson(), massey(), massey_duncan(), morgan_massey(), theil(), and white_blau() functions in vignettes and README
  • Added example for holder argument in atkinson() function in README
  • Added internal and external references within each functions documentation
  • Reordered and reformatted CITATION alphabetically by index abbreviation
  • Reordered the contents of 'ndi-package.R' thematically
  • Reordered the README examples alphabetically
  • Reordered the vignette examples to group the racial or ethnic residential segregation indices
  • Updated examples in vignettes to showcase a larger variety of U.S. states
  • Updated examples in functions to better describe the metrics
  • Updated documentation formatting of metric names in all functions
