Working with Control Breaks Data in R.

About a year ago, a young neighbor who's enrolled in an MS is Data Science program asked my help on an R coding exercise. The challenge was to compute several new category attributes based on columns in an initially loaded dataframe. His solution was to loop through each of the df rows, populating the new vars with basic if/then logic. Kind of reminded me of how I might…See More

AWK -- a Blast from Wrangling Past.

I recently came across an interesting account by a practical data scientist on how to munge 25 TB of data. What caught my eye at first was the article's title: "Using AWK and R to parse 25tb". I'm a big R user now and made a living with AWK 30 years ago as a budding data analyst. I also empathized with the author's recountings of his painful but steady education on…See More

Jobs, Unemployment and 45's Performance.

Despite the consuming controversy surrounding his presidency, POTUS 45 has been able to secure solid ratings on the performance of the economy over his so-far 30-month administration. And he certainly isn't bashful about taking credit for the successes, opining loudly and often that his tax cuts and de-regulation initiatives have significantly goosed the economy.45 has a…See More

Using Python and R to Load Relational Database Tables, Part I

I enjoy data prep munging for analyses with computational platforms such as R, Python-Pandas, Julia, Apache Spark, and even relational databases. The wrangling cycle provides the opportunity to get a feel for and preliminarily explore data that are to be later analyzed/modeled.A critical task I prefer handling in computation over database is data loading. This is because…See More
