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

- 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
