tsbox 0.2.1 (2020-04-29)

tsbox 0.2.0 (2019-08-06)

Features

• Construction of expressions for data.tables are done properly and now are able to contain spaces or non-ASCII characters (#151, thanks @stefanfritsch)
• ts_default() puts data frames in default order (ids, time, value) (#166)
• Consistent handling of non-default colnames and colorder in data frames (#166)
• Support for ‘tis’ time series (#150)
• Support for ‘irts’ time series, from package tseries
• Tweaks to color schemes

Bug fixes

tsbox 0.1.0 (2019-04-03)

Changes

• Rectangular structures (data.frame, tibble, data.table) keep explicit NAs by default. Use ts_na_omit() to make explicit NAs implicit. As previously, ts_regular() makes implicit NAs explicit.

New Functions and Features

• ts_default, new function to change column names to defaults (time, value), so that no auto detection is performed afterwards (#118)
• ts_summary, returns a data frame with summary information of a ts-boxable object. Also used to extract time series properties (ts_summary(x)$start, ts_summary(x)$freq, etc.)
• ts_regular gains fill argument, to specify replacement value for NA (#101)
• ts_pc, ts_pcy, ts_diff, ts_diffy have been rewritten and are much faster. They now return a series of the same length as the input, with NAs at the beginning.
• ts_pca, new function to calculate annualized percentage change rate
• ts_span gains extend argument, to add explicit NAs

Bug fixes

• ts_apply pass on arguments. This allows functions generated by ts_ to pass on additional arguments. E.g., ts_seas(AirPassengers, x11 = "") (#115, #103)
• unnamed tslist objects of length 1 don’t get an id anymore (#116)
• ts_span various fixes, boundary specification by shift string ("1 year") or period now works as expected, also for non-heuristic series, such as EuStockMarkets (#106)
• time column of daily data is treated as Date and survives two way conversion (#114, #137)
• ts_pick, error if picked series is not in data (#100)
• error when data contains duplicated series (#102)
• ts_plot, improved axis labels for high frequency series (#117)
• fixed tsibble to anything conversion

Deprecated

• ts_start, ts_end, use ts_summary(x)$start and ts_summary(x)$end instead.

tsbox 0.0.3 (2018-06-18)

Features

• Support for tibbletime time series (#90)

Bug fixes

• Automatically detect numbers or text from 1600 to 2200 as time column (#92)
• Fix to correctly ensure uniqueness of non unique id combinations (#93)
• Fix to correctly parse POSIXct columns for monthly data in different time zones. Remove two way testing for daily series with POSIXct columns. This should fix mac binary build on CRAN (#97)

tsbox 0.0.2 (2018-05-12)
