(math/R-xts) Updated 0.12.1 to 0.12.2
################################################################################ Changed in xts 0.12.2: o `Ops.xts()` no longer changes column names (via `make.names()`) when the two objects do not have identical indexes. This makes it consistent with `Ops.zoo()`. (#114) o Subsetting a zero-length xts object now returns an object with the same storage type as the input. It previously always returned a 'logical' xts object. (#376) o `tclass()` and `tzone()` now return the correct values for zero-length xts objects, instead of the defaults in the `.xts()` constructor. Thanks to Andre Mikulec for the report and suggested patch! (#255) o `endpoints()` now always returns last observation. Thanks to GitHub user Eluvias for the report. (#300) o Ensure `endpoints()` errors for every 'on' value when `k < 1`. It was not throwing an error for `k < 1` for `on` of "years", "quarters", or "months". Thanks to Eluvias for the report. (#301) o Fix `window()` for yearmon and yearqtr indexes. In xts < 0.11-0, `window.zoo()` was dispatched when `window()` was called on a xts object because there was no `window.xts()` method. `window.zoo()` supports additional types of values for the `start` argument, and possibly other features. So this fixes a breaking change in xts >= 0.11-0. Thanks to GitHub user annaymj for the report. (#312) o Clarify whether `axTicksByTime()` returns index timestamps or locations (e.g. 1, 2, 3). Thanks to @ggrothendieck for the suggestion and feedback. (#354) o Fix merge on complex types when 'fill' is needed. `merge()` would throw an error because it treated 'fill' as double instead of complex. Thanks to @ggrothendieck for the report. (#346) o Add a message to tell the user how to disable 'xts_check_TZ' warning. Thanks to Jerzy Pawlowski for the nudge. (#113) o Update `rbind()` to handle xts objects without dim attribute. `rbind()` threw an obscure error if one of the xts objects does not have a dim attribute. We can handle this case even though all xts objects should always have a dim attribute. (#361) o `split.xts()` now always return a named list, which makes it consistent with `split.zoo()`. Thanks to Gabor Grothendieck for the report. (#357) o xts objects with a zero-length POSIXct index now return a zero-length POSIXct vector instead of a zero-length integer vector. Thanks to Jasper Schelfhout for the report and PR! (#363, #364) o Add suffixes to output of `merge.xts()`. The suffixes are consistent with `merge.default()` and not `merge.zoo()`, because `merge.zoo()` automatically uses "." as a separator between column names, but the default method doesn't. Thanks to Pierre Lamarche for the nudge. Better late than never? (#38, #371) Changes to plotting functionality -------------------------------------------------------------------------------- o You can now omit the data time range from the upper-right portion of a plot by setting `main.timespan = FALSE`. (#247) o Fix `addEventLines()` when plotted objects have a 'yearmon' index. The ISO-8601 range string was not created correctly. Thanks to @paessens for the report. (#353) o Make 'ylim' robust against numerical precision issues by replacing `==` with `all.equal()`. Thanks to @bollard for the report, PR, and a ton of help debugging intermediate solutions! (#368) o Series added to a panel now extend the panel's y-axis. Previously the y-axis limits were based on the first series' values and not updated when new series were added. So values of the new series did not appear on the plot if they were outside of the original series' min/max. Thanks to Vitalie Spinu for the report and help debugging and testing! (#360) o All series added to any panel of a plot now update the x-axis of all panels. So the entire plot's x-axis will include every series' time index values within the original plot's time range. This behavior is consistent with `chart_Series()`. Thanks to Vitalie Spinu for the report and help debugging and testing! (#360, #216) o All y-values are now plotted for series that have duplicate index values, but different data values. Thanks to Vitalie Spinu for the report and help debugging and testing! (#360) o Adding a series can now extend the x-axis before/after the plot's existing time index range, so all of the new series' time index values are included in the plot. This is FALSE by default to maintain backward compatibility. Thanks to Vitalie Spinu for the report and help debugging and testing! (#360)
