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.

A new version of quantmod is on CRAN! One really cool thing about this release is that almost all the changes are contributions from the community.

I pushed an updated microbenchmark to CRAN a couple weeks ago. There were two noteworthy changes, thanks to great contributions from @MichaelChirico and @harvey131.

I just pushed a new release of quantmod to CRAN! getSymbols() no longer stops if there’s a problem with a ticker symbol. And getQuote() can now import quotes from Tiingo.

xts version 0.11-2 was published to CRAN yesterday. This is quick a bug-fix release.

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!

Someone recently shared this great talk by Chris Allen from lambda conf 2017.  The title of the talk is “Why Johnny Can’t Code Good,” but the content is more about how to grow as a programmer.  His points are true whether you’re just starting out, or have been coding for years.

This year marks the 10th anniversary of the R/Finance Conference! As in prior years, we expect more than 250 attendees from around the world. R users from industry, academia, and government will joining 50+ presenters covering all areas of finance with R. The conference will take place on June 1st and 2nd, at UIC in Chicago. You can find registration informationon the conference website, or you can go directly to the Cvent registration page.

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.

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).
