Half-Weight Index Gregariousness.

hwig

Calculates the half-weight index gregariousness (HWIG) as described in Godde et al. (2013) [1].

Installation

devtools::install_gitlab('robit.a/hwig')

# CRAN
install.packages('hwig')

Usage

# Load packages
library(hwig)
library(data.table)

# Load example data
DT <- fread(system.file("extdata", "DT.csv", package = "hwig"))

# Calculate HWI
hwi <- calc_hwi(DT, 'id', 'group', 'yr')
#> Generating  10  x  10  matrix
#> Generating  10  x  10  matrix

# Calculate HWIG
hwig <- calc_hwig(hwi)

# Set names
nms <- get_names(DT, 'yr')
names(hwig) <- nms

# Print first year's result
