#' Little Rock Lake zooplankton dataset
#'
#' Contains time series for 10 dominant crustaceous species of zooplanking
#' sampled from Little Rock Lake, Wisconsin. Samples come from two basins: one
#' treated to lower pH and the other an untreated reference.

#' \tabular{ll}{ Package: \tab mvcwt\cr Type: \tab Package\cr Version: \tab
#' 1.0\cr Date: \tab 2013-10-27\cr License: \tab GPL\cr } The main functions
#' are \code{\link{mvcwt}}, which computes the wavelet transform of multiple
#' time series, and \code{\link{wmr}}, which computes the wavelet modulus
#' ratio, a measure of time series coherence.
#'
#' Note that this is a complete rewrite of the code used in the reference
#' below, and as such it is not well tested. It may give different or
#' inaccurate results. I recommend you run tests on known data.
