Stream Network Movement Analyses R package SNMA version 0.1.5 Calculating home ranges and movements of animals in complex stream environments is often challenging, and standard home range estimators do not apply. This package provides a series of tools for assessing movements in a stream network, such as calculating the total length of stream used, distances between points, and movement patterns over time. See Vignette for additional details. This package was originally released on 'GitHub' under the name 'SNM'. SNMA was developed for analyses in McKnight et al. (2025) <doi:10.3354/esr01442> which contains additional examples and information. Software Depends: R (>= 3.5) Imports: sf,geosphere,igraph Suggests: ggplot2, ggnewscale, knitr,rmarkdown Donald T.
