xts version 0.11-1 was published to CRAN this morning. xts provides data structure and functions to work with time-indexed data. This release contains some awesome features that will transparently make your xts code even faster!Want to share your content on R-bloggers? click here if you have a blog, or here if you don't.
- There’s a new
window.xts()
method, thanks to Corwin Joy (#100, #240). Corwin also refactored and improved the performance of the binary search algorithm used to subset xts objects. Tom Andrews reported and fixed a few related regressions (#251, #263, #264). - The
na.locf.xts()
method loops over columns of multivariate objects in C code, for improved speed and memory performance. Thanks to Chris Katsulis and Tom Andrews for their reports and patches (#232, #233, #234, #235, #237). - After many years,
merge.xts()
can finally handle multiple character or complex xts objects. Thanks to Ken Williams for the report (#44). - You can use “quarters” to specify tick/grid mark locations on plots. Thanks to Marc Weibel for the report (#256).
make.index.unique()
always returns a unique and sorted index. Thanks to Chris Katsulis for the report and example (#241).- Plots have better axis tick mark locations, thanks to Dirk Eddelbuettel (#246).
periodicity()
now warns instead of errors if the xts object contains less than 2 observations (#230).first()
andlast()
now keep dims when they would otherwise be dropped by a regular row subset. This is consistent withhead()
andtail()
. Thanks to Davis Vaughan for the report (#226).- An invalid ISO8601 range subset now returns no data instead of all rows (#96).
