An updated version of xts reached CRAN on 2020-09-09. Time-of-day subsetting (e.g. x["T10:00/T13:00"]) is 200x faster! (This post includes some notes on some nifty changes in 0.12.0 too, since I didn’t post about 0.12.0 when it was released.)

TTR_0.24.2 on CRAN

An updated version of TTR is on CRAN now. This is mainly a bug-fix release. There were several issues in the underlying C code that caused various issues. I’ll spare you the gory details. If you’re really interested, you can find them in the CHANGES file.

Goodbye Google, Hello Tiingo!

First, the bad news: Google Finance no longer provides data for historical prices or financial statements, so we say goodbye to getSymbols.google() and getFinancials.google(). (#221) They are now defunct as of quantmod 0.4-13. Now, the good news: Thanks to Steve Bronder, getSymbols() can now import data from Tiingo! (#220) This feature is part of quantmod 0.4-13, which is now on CRAN. Windows and Mac binaries should be built in a day or two.

xts 0.10-2 on CRAN

This xts release contains mostly bugfixes, but there are a few noteworthy features. Some of these features were added in version 0.10-1, but I forgot to blog about it. Anyway, in no particular order: endpoints() gained sub-second accuracy on Windows (#202)! na.locf.xts() now honors x and xout arguments by dispatching to the next method (#215). Thanks to Morten Grum for the report. na.locf.xts() and na.omit.xts() now support character xts objects. Thanks to Ken Williams and Samo Pahor for the reports (#42).
