5.2 zcjs: Zero-crossing File Visualisation

The zcjs JavaScript library was originally developed for displaying zero-crossing audio files (1.3.3) on the web as part of the BioAcoustica project (https://bio.acousti.ca; Baker et al. (2015)). The zcjs package (Baker 2022) imports this visualisation functionality into R.

The following code installs the zcjs package.

install.packages("devtools")
devtools::install_github("bioacoustica/zcjs-r")

To load the package:

library(zcjs)

The package comes with a demonstration file for testing the package’s functionality.
