tslist function

Coerce matrices or data frames to a list of time series

Change a matrix or data frame to a list of univariate time series

tslist(series, simplify = FALSE)

Arguments

• series: A matrix or data frame where each row is a time series.
• simplify: Coerce all series in the resulting list to either matrix (multivariate) or numeric (univariate).

Returns

A list of time series.

Details

Almost all functions in dtwclust work internally with lists of time series. If you want to avoid constant coercion, create a list of time series once by calling this function.

For matrices and data frames, each row is considered as one time series. A list input is simply passed through.

Note

The function assumes that matrix-like objects can be first coerced via base::as.matrix(), so that the result can be indexed with series[i, ].

No consistency checks are performed by this function.
