Package: HLCtools Title: Calculate Herd Lying Concordance Metrics Version: 0.1.0 Authors@R: person( given = "Guilherme", family = "Amorim Franchi", email = "gaf@anivet.au.dk", role = c("aut", "cre", "cph"), comment = c(ORCID = "0000-0001-7653-6512") ) Description: Calculates Herd Lying Concordance (HLC) metrics from individual animal lying-behaviour data. HLC is a continuous framework for quantifying group-level behavioural cohesion from between-animal dispersion within observation intervals. The package implements standard deviation, mean absolute deviation, interquartile range, and entropy formulations, lying-weighted extensions, threshold-based synchrony comparisons, temporal summaries, and descriptive method-ranking tools. The HLC formulations are introduced in this package; related approaches to cattle behavioural synchrony include Raussi et al. (2011) , Kok et al. (2023) , and the activity metric framework of van Dixhoorn et al. (2024) .
