dang 0.0.13: New intradayMarketMonitor

sp500 intraday monitor

A new release of the dang package got to CRAN earlier today, a few months since the last relase. The dang package regroups a few functions of mine that had no other home as for example lsos() from a StackOverflow question from 2009 (!!) is one, this overbought/oversold price band plotter from an older blog post is another.

This release adds one function I tweeted about one month ago. It takes a function Josh Ulrich originally tweeted about in November with a reference to this gist. I refactored this into a proper functions and polished a few edges: the data now properly rolls off after a fixed delay (of two days), should work with other symbols (though we both focused on ^GSPC as a free (!!) real-time SP500 index (albeit only during trading hours), properly gaps between trading days and more. You can simply invoke it via

dang::intradayMarketMonitor()

and a chart just like the one here will grow (though there is no “state”: if you stop it, or reboot, or … the plot starts from scratch).

The short NEWS entry follows.

Changes in version 0.0.13 (2021-02-17)

  • New function intradayMarketMonitor based on an earlier gist-posted snippet by Josh Ulrich.

  • The CI setup was generalized as a test for 'r-ci' and is used essentially unchanged with three different providers.

Courtesy of my CRANberries, there is a comparison to the previous release. For questions or comments use the issue tracker off the GitHub repo.

If you like this or other open-source work I do, you can now sponsor me at GitHub.

dang 0.0.12: Two new functions

A new release of the dang package is now on CRAN, roughly one year after the last release. The dang package regroups a few functions of mine that had no other home as for example lsos() from a StackOverflow question from 2009 (!!) is one, this overbought/oversold price band plotter from an older blog post is another. More recently added were helpers for data.table to xts conversion and a git repo root finder.

This release adds two functions. One was mentioned just days ago in a tweet by Nathan and is a reworked version of something Colin tweeted about a few weeks ago: a little data wrangling off the kewl rtweet to find maximally spammy accounts per search topic. In other words those who include more than ‘N’ hashtags for given search term. The other is something I, if memory serves, picked up a while back on one of the lists: a base R function to identify non-ASCII characters in a file. It is a C function that is not directly exported by and hence no accessible, so we put it here (with credits, of course). I mentioned it yesterday when announcing tidyCpp as I this C function was the starting point for the new tidyCpp wrapper around some C API of R functions.

The (very short) NEWS entry follows.

Changes in version 0.0.12 (2020-10-14)

  • New functions muteTweets and checkPackageAsciiCode.

  • Updated CI setup.

dang 0.0.11: Small improvements

A new release of what may be my most minor package, dang, is now on CRAN. The dang package regroups a few functions of mine that had no other home as for example lsos() from a StackOverflow question from 2009 (!!) is one, this overbought/oversold price band plotter from an older blog post is another. More recently added were helpers for data.table to xts conversion and a git repo root finder.

Some of these functions (like lsos()) where hanging in my .Rprofile, other just lived in scripts so some years ago I started to collect them in a package, and as of February this is now on CRAN too for reasons that are truly too bizarre to go about. It’s a weak and feeble variant of the old Torvalds line about backups and ftp sites …

As I didn’t blog about the 0.0.10 release, the NEWS entry for both follows:

Changes in version 0.0.11 (2019-10-24)

  • New functions getGitRoot, inGit and isConnected.

  • Improved function as.data.table.xts.

Changes in version 0.0.10 (2019-02-10)

  • Initial CRAN release. See ChangeLog for earlier changes.
