Add Dressbarn to the Continued Retailpocalypse

I’ve talked about the retailpocalypse before and this morning I was greeted with the news about Dressbarn closing all 650 stores as I fired up a browser. I tweeted some pix and data but not everyone is on Twitter so I’m just posting a blog-blurb here with the code and data links. Code is below... Continue reading →

Mapping Tornado Alley with R

I caught a re-tweet of this tweet by @harry_stevens: THREAD: I wrote a post on @observablehq about a map I made today. It shows a typical day in the life of a graphics journalist: You never know what problems you'll have to solve on deadline! https://t.co/yRhW1wbLxN #d3js #dataviz 1/7 pic.twitter.com/7N6mmK0nz3 — Harry Stevens (@Harry_Stevens) May...

Quick Hit: Updates to QuickLookR and {rdatainfo}

I’m using GitUgh links here b/c the issue was submitted there. Those not wishing to be surveilled by Microsoft can find the macOS QuickLook plugin project and {rdatainfo} project in SourceHut and GitLab (~hrbrmstr and hrbrmstr accounts respectively). I hadn’t touched QuickLookR🔗 or {rdatainfo}🔗 at all since 2016 since it was really just an example... Continue reading →

Quick Hit: Scraping javascript-“enabled” Sites with {htmlunit}

I’ve mentioned {htmlunit} in passing before, but did not put any code in the blog post. Since I just updated {htmlunitjars} to the latest and greatest version, now might be a good time to do a quick demo of it. The {htmlunit}/{htmunitjars} packages make the functionality of the HtmlUnit Java libray available to R. The... Continue reading →

Lost In [SQL] Translation: Charting d[b]plyr Mapped SQL Function Support Across All Backends

Like more posts than I care to admit, this one starts innocently enough with a tweet by @gshotwell: Is there a reference document somewhere of which dplyr commands work on various database backends? #rstats — Gordon Shotwell (@gshotwell) April 9, 2019 Since I use at least 4 different dplyr backends every week, this same question...

A Limited-but-Functional Couchbase Free Text Search & Retrieval Un-package; or, “How I Abused Couchbase & R to Perform Bulk IP Whois Full-text Searches” (a Cobbler’s Tale)

A Limited-but-Functional Couchbase Free Text Search & Retrieval Un-package; or, “How I Abused Couchbase & R to Perform Bulk IP Whois Full-text Searches” (a Cobbler’s Tale)

Researching “the internet” (i.e. $DAYJOB) means having to deal with a ton of “unique” (I’m being kind) data formats. This is ultimately a tale of how I performed full-text searches across one of them. It all started off innocently enough. This past week I need to be able to do full-text searches across metadata about... Continue reading →

Wicked Fast, Accurate Quantiles Using ‘t-Digests’ in R with the {tdigest} Package

April 3, 2019
By

@ted_dunning recently updated the t-Digest algorithm he created back in 2013. What is this “t-digest”? Fundamentally, it is a probabilistic data structure for estimating any percentile of distributed/streaming data. Ted explains it quite elegantly in this short video: Said video has a full transcript as well. T-digests have been baked into many “big data” analytics... Continue reading →

Rome Was Not Built In A Day But widgetcard Was!

I saw a second post on turning htmlwidgets into interactive Twitter Player cards and felt somewhat compelled to make creating said entities a bit easier so posited the following: Wld this be useful packaged up, #rstats?https://t.co/sfqlWnEeJVhttps://t.co/troKzmzTNv (TLDR/V: Single function to turn an HTML widget into a deployable interactive Twitter card) pic.twitter.com/uahB52YfE2 — boB Rudis (@hrbrmstr)...

Assumptions Matter More Than Dependencies

March 18, 2019
By

There’s been alot of talk about “dependencies” in the R universe of late. This is not really a post about that but more of a “really, don’t do this” if you decide you want to poke the dependency bear by trying to build a deeply flawed model off of CRAN package metadata. CRAN packages undergo... Continue reading →

Handling & Sharing PCAPs Like a Boss with PacketTotal

March 17, 2019
By

The fine folks over at @PacketTotal bequeathed an API token on me so I cranked out an R package for it to enable more dynamic investigations work (RStudio makes for an amazing incident responder investigations console given that you can script in multiple languages, code in C, and write documentation all at the same time...
