Time lag analysis for a multivariate data set

timelag(x, ...)

## S3 method for class 'dist'
timelag(x, ...)

`x`	an R object. Only objects of class `"dist"` are currently supported.
`...`	additional arguments passed to other methods.

Time lag analysis involves computing the compositional dissimilarity between samples at lag 1, at lag 2, etc, then the least squares slope between sqrt(lag) and dissimilarity.

Returns an object of class "timelagAnalysis", a list with components

data: data frame; unpacked set of lags (Lag) and compositional dissimilarities (Distance).
