tsbox (version 0.3.1)

ts_examples: Principal Components, Dygraphs, Forecasts, Seasonal Adjustment

Description

Example Functions, Generated by ts_. ts_prcomp calculates the principal components of multiple time series, ts_dygraphs generates an interactive graphical visualization, ts_forecast return an univariate forecast, ts_seas the seasonally adjusted series. ts_na_interpolation imputes missing values.

Usage

ts_prcomp(x, ...)
ts_dygraphs(x, ...)
ts_forecast(x, ...)
ts_seas(x, ...)
ts_na_interpolation(x, ...)

Value

Usually, a ts-boxable time series, with the same class as the input. ts_dygraphs draws a plot.

Arguments

x

ts-boxable time series, an object of class ts, xts, zoo, data.frame, data.table, tbl, tbl_ts, tbl_time, tis, irts or timeSeries.

...

further arguments, passed to the underlying function. For help, consider these functions, e.g., stats::prcomp.

Details

With the exception of ts_prcomp, these functions depend on external packages.
