May 19, 2018 | r on Tony ElHabr

Competition Participation Some of the first questions that might come to mind are those regarding the number of schools in each level of competition (District, Region, and State) and each conference classification level (1A, 2A, … 6A).

May 19, 2018 | r on Tony ElHabr

Having investigated individuals elsewhere, let’s now take a look at the schools. NOTE: Although I began the examinations of competitions and individuals by looking at volume of participation (to provide context), I’ll skip an analogous discussion here because the participation of schools is shown indirectly through those analyses.) ...

May 19, 2018 | r on Tony ElHabr

NOTE: This is part of a series of write-ups discussing my findings of Texas high school academic University Interscholastic Scholarship (UIL) competitions.

May 4, 2018 | r on Tony ElHabr

Don’t Repeat Yourself (DRY) Probably everyone who has done some kind of programming has heard of the “Don’t Repeat Yourself” (DRY) principle.

April 29, 2018 | r on Tony ElHabr

I’ve experimented with the {flexdashboard} package for a couple of things after first trying out not so long ago. In particular, I found the storyboard format to be my favorite. I used it to create the storyboard that I wrote about in a previous post about tracking the activity ...

Investigating Ranks, Monotonicity, and Spearman’s Rho with R

April 15, 2018 | r on Tony ElHabr

The Problem I have a bunch of data that can be categorized into many small groups. Each small group has a set of values for an ordered set of intervals. Having observed that the values for most groups seem to increase with the order of the interval, I hypothesize that ...

Analyzing Professional Sports Team Colors with R, Part 2

March 31, 2018 | r on Tony ElHabr

NOTE: This write-up picks up where the previous one left off. All of the session data is carried over. Color Similarity Now, I’d like to evaluate color similarity more closely. To help verify any quantitative deductions with some intuition, I’ll consider only a single league for this–the ...

Analyzing Professional Sports Team Colors with R

March 30, 2018 | r on Tony ElHabr

When working with the ggplot2 package, I often find myself playing around with colors for longer than I probably should be. I think that this is because I know that the right color scheme can greatly enhance the information that a plot portrays; and, conversely, choosing an uncomplimentary palette can ...

March 10, 2018 | r on Tony ElHabr

I just wrapped up a mini-project that allowed me to do a handful of things I’ve been meaning to do: Try out the {flexdashboard} package, which is supposed to be good for prototypying larger dashboards (perhaps created with {shinydashboard}. Test out my (mostly completed) personal {tetext} package for quick ... [Read more...]

A Tidy Text Analysis of R Weekly Posts

March 4, 2018 | r on Tony ElHabr

I’m always intrigued by data science “meta” analyses or programming/data-science. For example, Matt Dancho’s analysis of renown data scientist David Robinson. David Robinson himself has done some good ones, such as his blog posts for Stack Overflow highlighting the growth of “incredible” growth of python, and the “...

February 18, 2018 | r on Tony ElHabr

In this post, I’ll continue my discussion of working with regularly sampled interval data using R. (See my previous post for some insight regarding minute data.) The discussion here is focused more so on function design. Daily Data When I’ve worked with daily data, I’ve found that ...

February 16, 2018 | r on Tony ElHabr

In my job, I often work with data sampled at regular intervals. Samples may range from 5-minute intervals to daily intervals, depending on the specific task. While working with this kind of data is straightforward when its in a database (and I can use SQL), I have been in a ...

A Tidy Text Analysis of My Google Search History

February 15, 2018 | r on Tony ElHabr

While brainstorming about cool ways to practice text mining with R I came up with the idea of exploring my own Google search history. Then, after googling (ironically) if anyone had done something like this, I stumbled upon Lisa Charlotte’s blog post. Lisa’s post (actually, a series of ...

Personal Coding Conventions

February 9, 2018 | r on Tony ElHabr

As a person who’s worked with various programming languages over time, I have become interested in the nuances and overlaps among languages.

If you’re not completely new to the data science community (specifically, the #rstats community), then you’ve probably seen a version of the “famous” data science workflow diagram. 1 If one is fairly familiar with a certain topic, then one might not spend much time with the initial “visualize” step ...
