Diving Into Dynamic Website Content with splashr

February 9, 2017 | hrbrmstr

If you do enough web scraping, you’ll eventually hit a wall that the trusty httr verbs (that sit beneath rvest) cannot really overcome: dynamically created content (via javascript) on a site. If the site was nice enough to use XHR requests to load the dynamic content, you can generally ...

Strung Out On String Ops – A Brief Comparison of stringi and stringr

February 5, 2017 | hrbrmstr

I made a promise to someone that my next blog would be about stringi vs stringr and I intend to keep said promise. stringr and stringi do “string operations”: find, replace, match, extract, convert, transform, etc. The stringr package is now part of the tidyverse and is 100% focused on string ...

Candy Coated Confidence Intervals

February 3, 2017 | hrbrmstr

@mrshrbrmstr hinted that she would like this post by @RickWicklin translated into R for her stats class. She’s quite capable of cranking out the translation of the core component of that post — a call to chisq.test — but she wanted to show the entire post (in R) and really ... [Read more...]

Exploring News Coverage With newsflash

February 1, 2017 | hrbrmstr

I was enthused to see a mention of this on the GDELT blog since I’ve been working on an R package dubbed newsflash to work with the API that the form front-ends. Given the current climate, I feel compelled to note that I’m neither a Clinton supporter/defender/...

One View of the Impact of the New Immigration Ban (+ freeing PDF data with tabulizer)

January 26, 2017 | hrbrmstr

Dear Leader has made good on his campaign promise to “crack down” on immigration from “dangerous” countries. I wanted to both see one side of the impact of that decree — how many potential immigrants per year might this be impacting — and show toss up some code that shows how to ...

Create Parquet Files From R Data Frames With sergeant & Apache Drill (a.k.a. Make Parquet Files Great Again in R)

January 22, 2017 | hrbrmstr

Apache Drill is a nice tool to have in the toolbox as it provides a SQL front-end to a wide array of database and file back-ends and runs in standalone/embedded mode on every modern operating system (i.e. you can get started with or play locally with Drill w/... [Read more...]

Workout Wednesday Redux (2017 Week 3)

January 18, 2017 | hrbrmstr

I had started a “52 Vis” initiative back in 2016 to encourage folks to get practice making visualizations since that’s the only way to get better at virtually anything. Life got crazy, 52 Vis fell to the wayside and now there are more visible alternatives such as Makeover Monday and Workout Wednesday. ...

Knit directly to jupyter notebooks from RStudio

January 10, 2017 | hrbrmstr

Did you know that you can completely replace the “knitting” engine in R Markdown documents? Well, you can! Why would you want to do this? Well, in the case of this post, to commit the unpardonable sin of creating a clunky jupyter notebook from a pristine Rmd file. I’m ... [Read more...]

2017-01 Authored Package Updates

January 8, 2017 | hrbrmstr

The rest of the month is going to be super-hectic and it’s unlikely I’ll be able to do any more to help the push to CRAN 10K, so here’s a breakdown of CRAN and GitHub new packages & package updates that I felt were worth raising awareness on: ...

The Most Important Commodity in 2017 is Data

January 5, 2017 | hrbrmstr

Despite being in cybersecurity nigh forever (a career that quickly turns one into a determined skeptic if you’re doing your job correctly) I have often trusted various (not to be named) news sources, reports and data sources to provide honest and as-unbiased-as-possible information. The debacle in the U.S. ...

Removing Personal Bias From Flu Severity Estimation (a.k.a. Misery Loves Data)

January 2, 2017 | hrbrmstr

The family got hit pretty hard with the flu right as the Christmas festivities started and we were all pretty much bed-ridden zombies up until today (2017-01-02). When in the throes of a very bad ILI it’s easy to imagine that you’re a victim of a severe ...

Pipes (%>%) Everywhere

December 22, 2016 | hrbrmstr

An R user asked a question regarding whether it’s possible to have the RStudio pipe (%__%) shortcut (Cmd-Shift-M) available in other macOS applications. If you’re using Alfred then you can use this workflow for said task (IIRC this requires an Alfred license which is reasonably cheap). When you add ... [Read more...]

December 20, 2016 | hrbrmstr

I recently mentioned that I’ve been working on a development version of an Apache Drill R package called sergeant. Here’s a lifted “TLDR” on Drill: Drill supports a variety of NoSQL databases and file systems, including HBase, MongoDB, MapR-DB, HDFS, MapR-FS, Amazon S3, Azure Blob Storage, Google Cloud ...

Package update: longurl 0.3.0 is hitting CRAN mirrors

December 18, 2016 | hrbrmstr

The longurl package has been updated to version 0.3.0 as a result of a bug report noting that the URL expansion API it was using went pay-for-use. Since this was the second time a short URL expansion service either went belly-up or had breaking changes the package is now completely client-side-based ...

Minding the zoo[keeper] with R

December 16, 2016 | hrbrmstr

I’ve been drafting a new R package — sergeant — to work with Apache Drill and have found it much easier to manage having Drill operating in a single node cluster vs drill-embedded mode (esp when I need to add a couple more nodes for additional capacity). That means running Apache ... [Read more...]

Interacting With Amazon Athena from R

December 5, 2016 | hrbrmstr

This is a short post for those looking to test out Amazon Athena with R. Amazon makes Athena available via JDBC, so you can use RJDBC to query data. All you need is their JAR file and some setup information. Here’s how to get the JAR file to the ... [Read more...]

The ASA (American Statistical Association) has been working in collaboration with the ACM (Association for Computing Machinery) on developing a data science curriculum for Two Year Colleges.

Counting [U.S.] Expatriation with R (a.k.a. a Decade of Desertion)

August 8, 2016 | hrbrmstr

If you’re even remotely following the super insane U.S. 2016 POTUS circus election you’ve no doubt seen a resurgence of “if X gets elected, I’m moving to Y” claims by folks who are “anti” one candidate or another. The Washington Examiner did a story on last quarter’...

QuickLookR – A macOS QuickLook plugin for R Data files

August 6, 2016 | hrbrmstr

I had tried to convert my data-saving workflows to feather but there have been issues with it supporting large files (that seem to be near resolution), so I’ve been continuing to use R Data files for local saving of processed/cleaned data. I make many of these files and ...
