In ggtime: Grammar of Graphics and Plot Helpers for Time Series Visualization

ggtime 0.2.0

This release completes the migration of graphics functions from {feasts} and {fabletools}, including a deprecation process for a gradual migration to {ggtime}. If you previously used time-series graphics from {feasts} or {fable}, you should now include library(ggtime) in your script to avoid deprecation notices. Existing code will continue to work with a deprecation warning.

The following plot helper functions from {fabletools} are included in this release:

autoplot(<fbl_ts>): Forecast plots to show forecast intervals with historical data.
autolayer(<fbl_ts>): Forecast layers for fable objects.
autoplot(<dcmp_ts>): Decomposition plots to show components of a dable object.
fortify(<fbl_ts>): Fortify method for converting fable objects into basic data frames.

ggtime 0.1.0

Initial release including all plot helper functions from across the tidy time series analysis packages. The following plot helper functions are included in this release:

autoplot(<tbl_ts>): Time plots to show overall patterns in tsibble objects.
autolayer(<tbl_ts>): Time plot layers for tsibble objects.
gg_season(): Seasonal plots to show the shape of seasonal patterns.
gg_subseries(): Seasonal sub-series plots to show seasonal changes over time.
gg_lag(): Lag plots to show relationships between now and the past.
gg_irf(): Impulse response function plots to be used with IRF() results.
gg_arma(): Plot the characteristic ARMA roots.
gg_tsdisplay(): An ensemble graphic useful in exploring time series data.
gg_tsresiduals(): An ensemble graphic useful in diagnosing model residuals.
