These data will be used in my segment of a Linear Regression basics talk I am doing Tuesday, September 25, 2018 with Kevin Feasel at Vaco Raleigh. Register for free HERE (may have to join the group first, also free). A few data concerns that caused my prior output to be flawed: Walking events caused […]
I am preparing with TriPASS leader, Kevin Feasel, a data science talk discussing Linear Regression for Tuesday, September 25th at Vaco Raleigh (near PNC Arena). Part of my presentation will explore the prediction of track running times during this Summer’s Carolina Godiva Track Club Summer Track Series (2018). I have written a few blog posts […]
[Thank you Dr. Di Cook for featuring this blog post among the Project:Data Stories on your ETC 1010: Data Modelling and Computing webpage]. I am voluntarily helping a friend, Carl Lanore, with Facebook advertising for his business, Super Human Radio Network – featuring the health / physical culture-focused podcast, Super Human Radio. This is a […]
With an hour remaining until the final Carolina Godiva Track Club Summer Track Series all-comers track meet, let’s dash out a blog post as if more excitement was needed. Having created the R data frame (track_res_all) with the 2018 results via the code at the bottom of the last blog post, it is my pleasure […]
Using Excel (.xls) files containing World Masters Athletics age-graded track tables on Howard Grubb’s website (http://www.howardgrubb.co.uk/athletics/data/wavacalc06.xls), I have an R data frame that stores age-graded track performances for this year’s Carolina Godiva Track Club Summer Track Series track meets. These are all-ages, all-abilities races hand-timed by volunteers and often begun by our fearless, ear-protecting, honorable […]

A personal goal is to contribute to the improvement of public health by encouraging more Americans to exercise. The Carolina Godiva Track Club, of which I […]
I use the R package openxlsx, by Sydney’s Alexander Walker, a few times per week. When professional stakeholders love Microsoft Excel, we give them the .XLSX workbooks that they seek. Using setColWidths (…, widths = “auto”)usually works to widen columns based on the values present in the workbook. However, I experienced earlier today a failure of this auto-widening feature. […]
[20190205 update: Registration is available for Analytics>Forward 2019 (LINK)! I think registrations are trending higher than last year so selling-out is a risk.] [Mara Averick (@dataandme) of #DataScience Twitter fame is keynoting Analytics>Forward 2018 in Durham, North Carolina on March 10, 2018. I hope to see you there.] Introduction I call this series “Play by play” because […]
In the spirit of Mara Averick’s (keynoting March 10, 2018 in Durham, NC!) “contributing to the tidyverse” presentation at rstudio::conf 2018 (PDF slides here). This is a play-by-play of my work to update another’s R package that hopefully will stimulate others to get involved in the open-source community and teach an important lesson by example. […]
Attending data science networking / training events consistently triggers me to learn stuff I otherwise would not have, regardless of what material is available online. The following use of R (#rstats) to download “YES” RSVPs for the past four years’ Analytics Forward was greatly inspired by hearing RTP actuarial expert, Brian Fannin, present “Go Ape for […]
