OS Secrets Exposed: Extracting Extended File Attributes and Exploring Hidden Download URLs With The xattrs Package

May 30, 2018 | hrbrmstr

Most modern operating systems keep secrets from you in many ways. One of these ways is by associating extended file attributes with files. These attributes can serve useful purposes. For instance, macOS uses them to identify when files have passed through the Gatekeeper or to store the URLs of files ...

The Fix Is In: Finding infix functions inside contributed R package “utilities” files

May 29, 2018 | hrbrmstr

Regular readers will recall the “utility belt” post from back in April of this year. This is a follow-up to a request made asking for a list of all the % infix functions in those files. We’re going to: collect up all of the sources parse them find all the ... [Read more...]

The Power of Standards and Consistency

May 26, 2018 | hrbrmstr

I’m going to (eventually) write a full post on the package I’m mentioning in this one : osqueryr🔗. The TLDR on osqueryr is that it is an R DBI wrapper (that has just enough glue to also be plugged into dbplyr) for osquery🔗. The TLDR on osquery is that ...

Create Code Metrics with cloc

May 19, 2018 | hrbrmstr

The cloc Perl script (yes, Perl!) by Al Danial (https://github.com/AlDanial/cloc) has been one of the go-to tools for generating code metrics. Given a single file, directory tree, archive, or git repo, cloc can speedily give you metrics on the count of blank lines, comment lines, and ...

‘LMX ot NOSJ!’ Interchanging Classic Data Formats With Single `blackmagic` Incantations

May 18, 2018 | hrbrmstr

The D.C. Universe magic hero Zatanna used spells (i.e. incantations) to battle foes and said spells were just sentences said backwards, hence the mixed up jumble in the title. But, now I’m regretting not naming the package zatanna and reversing the function names to help ensure they’...

Wrangling Data Table Out Of the FBI 2017 IC3 Crime Report

May 8, 2018 | hrbrmstr

The U.S. FBI Internet Crime Complaint Center was established in 2000 to receive complaints of Internet crime. They produce an annual report, just released 2017’s edition, and I need the data from it. Since I have to wrangle it out, I thought some folks might like to play long at ...

Seventeen Minutes From Tweet To Package

May 3, 2018 | hrbrmstr

Earlier today, @noamross posted to Twitter: #rstats #lazyweb What's the R/httr/curl equivalent of curl -F "[email protected]" https://t.co/abbugLz9ZW — Noam Ross (@noamross) May 3, 2018 The answer was a 1:1 “file upload” curl to httr translation: but I wanted to do more than that since Noam took 20 ...

Painless ODBC + dplyr Connections to Amazon Athena and Apache Drill with R & odbc

April 20, 2018 | hrbrmstr

I spent some time this morning upgrading the JDBC driver (and changing up some supporting code to account for changes to it) for my metis package🔗 which connects R up to Amazon Athena via RJDBC. I’m used to JDBC and have to deal with Java separately from R so ...

Examining POTUS Executive Orders

April 18, 2018 | hrbrmstr

This week’s edition of Data is Plural had two really fun data sets. One is serious fun (the first comprehensive data set on U.S. evictions, and the other I knew about but had forgotten: The Federal Register Executive Order (EO) data set(s). The EO data is also ...

By Request: Retrieving Your Feedly “Saved for Later” Entries

April 16, 2018 | hrbrmstr

@mkjcktzn asked if one can access Feedly “Saved for Later” items via the API. The answer is “Yes!”, and it builds off of that previous post. You’ll need to read it and get your authentication key (still no package 😞) before continuing. We’ll use most (I think “all”) of ...

Does Congress Really Care About Your Privacy?

April 13, 2018 | hrbrmstr

I apologize up-front for using bad words in this post. Said bad words include “Facebook”, “Mark Zuckerberg” and many referrals to entities within the U.S. Government. Given the topic, it cannot be helped. I’ve also left the R tag on this despite only showing some ggplot2 plots and ...

Convert epub to Text for Processing in R

April 12, 2018 | hrbrmstr

@RMHoge asked the following on Twitter: Hello #rstats hyve mind! Is there a package that reads epub into R? I can not find any, I now convert to text and parse the text but you sort of lose the structure of the text. Pinging @dataandme @hrbrmstr — Roel (@RMHoge) April 12, 2018 Here’...

Dissecting R Package “Utility Belts”

April 8, 2018 | hrbrmstr

Many R package authors (including myself) lump a collection of small, useful functions into some type of utils.R file and usually do not export the functions since they are (generally) designed to work on package internals rather than expose their functionality via the exported package API. Just like Batman’...

Adding macOS Touch Bar Support to RStudio

April 6, 2018 | hrbrmstr

Modern MacBook Pros have a fairly useless (c’mon, admit it!) “Touch Bar” that did little more than cause severe ire in the developer community after turning a full-fledged, tactile Escape key into a hollow version if its former self. Having said, that, some apps do make OK use of ...

Exploring R-Bloggers Posts with the Feedly API

April 4, 2018 | hrbrmstr

There’s a yuge chance you’re reading this post (at least initially) on R-Bloggers right now (though you should also check out R Weekly and add their live feed to your RSS reader pronto!). It’s a central “watering hole” for R folks and is read by many (IIRC ...

More Options For Querying DNS From R with 1.1.1.1

April 1, 2018 | hrbrmstr

You have to have been living under a rock to not know about Cloudflare’s new 1.1.1.1 DNS offering. I won’t go into “privacy”, “security” or “speed” concepts in this post since that’s a pretty huge topic to distill for folks given the, now, plethora of confusing (and pretty ...

Compute/Visualize Drive Space Consumption of Your Installed R Packages

April 1, 2018 | hrbrmstr

The fs package makes it super quick and easy to find out just how much “package hoarding” you’ve been doing: While you can modify the above and peruse the list of packages/directories in tabular format or programmatically, you can also do a bit more work to get a ...

R⁶ — Capturing [YouTube] Captions

March 29, 2018 | hrbrmstr

(R⁶ == brief, low-expository posts) @yoniceedee suggested I look at the Cambridge Analytics “whistleblower” testimony proceedings: @hrbrmstr giving the term "improving r&d" a whole new meaning … https://t.co/f1KA8U3htT — yoni sidi (@yoniceedee) March 29, 2018 I value the resources @yoniceedee tosses my way (they often end me down ...

On MIMEs, software versions and web site promiscuity (a.k.a. three new packages to round out the week)

March 23, 2018 | hrbrmstr

A quick Friday post to let folks know about three in-development R packages that you’re encouraged to poke the tyres o[fn] and also jump in and file issues or PRs for. Alleviating aversion to versions I introduced a “version chart” in a recent post and one key element ...

Steel-ing a Makeover from Tariffic Post

March 12, 2018 | hrbrmstr

(FWIW I think I even caused myself pain due to the title of this blog post). Kaiser Fung (@junkcharts) did a makeover post on this chart about U.S. steel tariffs: Kaiser’s makeover is good (Note: just because I said “good” does not mean I’m endorsing the use ...
