Wavelet Approaches to Studies of Synchrony in Ecology and Other Fields

Tools for a wavelet-based approach to analyzing spatial synchrony, principally in ecological data. Some tools will be useful for studying community synchrony. See, for instance, Sheppard et al (2016) , Sheppard et al (2017) , Sheppard et al (2019) .

This repository provides tools for analyzing synchrony of time series from a timescale-specific viewpoint. The tools have so far principally been useful for studying spatial synchrony of population dynamics in ecology, but may be useful for a variety of other applications.


In addition to the documentation, see the vignette, which is the best way to get started.


For a quick install of this development version: devtools::install_github(repo="reumandc/wsyn"). The install_github function, by default, will not install the vignette. There is an option for installing vignettes (build_vignettes=TRUE), but it seems finicky. You can also clone the repository and use devtools::install() to install from your local clone. The build_vignettes=TRUE option seems to work better for devtools::install than it does for devtools::install_github. If you have trouble, please email me.

Running all tests

Some of the more intensive tests are skipped unless there is a variable in the global environment called RUN_INTENSIVE_TESTS which is TRUE. This is so CRAN checks will run in the allowed time on CRAN servers, and was requested by CRAN.
