add_index

Add a rowwise mean or sum index of specific variables to the dataset.

Provides convenience functions for common data
modification and analysis tasks in communication research. This
includes functions for univariate and bivariate data analysis, index
generation and reliability computation, and intercoder reliability
tests. All functions follow the style and syntax of the tidyverse, and
are construed to perform their computations on multiple variables at
once. Functions for univariate and bivariate data analysis comprise
summary statistics for continuous and categorical variables, as well
as several tests of bivariate association including effect sizes.
Functions for data modification comprise index generation and
automated reliability analysis of index variables. Functions for
intercoder reliability comprise tests of several intercoder
reliability estimates, including simple and mean pairwise percent
agreement, Krippendorff's Alpha (Krippendorff 2004, ISBN:
9780761915454), and various Kappa coefficients (Brennan & Prediger
1981 <doi: 10.1177/001316448104100307>; Cohen 1960 <doi:
10.1177/001316446002000104>; Fleiss 1971 <doi: 10.1037/h0031619>).
