Jedi SAS Tricks - Maximum Warp with Hadoop

I'm gearing up to teach the next "DS2 Programming Essentials with Hadoop" class, and thinking about Warp Speed DATA Steps with DS2 where I first demonstrated parallel processing using threads in base SAS. But how about DATA step processing at maximum warp? For that, we'll need a massively parallel processing [...]

SAS Enterprise Guide: Suppress Output Data tab when programming

Have you ever waited a bit for SAS Enterprise Guide to display the Output Data tab when submitting a SAS program that generates multiple output tables?  Or, perhaps your program only generates one big output table but it takes a little while for it to surface on the Output Data [...]

When reading a text file (common extensions: TXT, DAT; or, for the adventurous: HTML) with the DATA STEP, you should always view several lines from the text file, and compare to the record layout, before completing the INPUT statement.  There are many ways to view a text file.  I use [...]

Weird PROC FREQ trick

Default PROC FREQ output looks like this: Suppose you don't want the two cumulative statistic columns above.  No problem.  Those can be suppressed with the NOCUM option on the TABLE statement, like this: proc freq data=sashelp.shoes; table product / nocum; run; tags: learn sas, sas training, tips and tricks

How analytics saved the break room coffee machine

SAS software is used around the world in some of the most sophisticated ways, like ATM fraud detection and cancer research. But recently, I used it for a practical, and much needed, task -- replacing our break room coffee machine. Now, this is no ordinary coffee machine. It also makes [...]

Dataset too big for PROC PRINT?

Dataset too big for PROC PRINT? One weird trick solves your problem! proc print data=bigdata (obs=10); run; The OBS= dataset option specifies the last observation to process from an input dataset. In the above example, regardless of dataset size, only the first 10 observations are printed; an easy way to [...]

Jedi SAS Tricks: Warp Speed DATA Steps with DS2

I remember the first time I was faced with the challenge of parallelizing a DATA step process. It was 2001 and SAS V8.1 was shiny and new. We were processing very large data sets, and the computations performed on each record were quite complex. The processing was crawling along on [...]

When art and analytics collide

The best graphs are both beautiful and informative - a smooth blend of art and analytics. But more often than not, the two collide rather than blending smoothly... Here is a link to a artistic infographic I recently saw posted by Vendavo on twitter. Their message (80% of your profit is generated [...]

I can see clearly now thanks to this SAS student

With any software program, there are always new tips and tricks to learn, and nobody can know them all. Sometimes I even pick up tips or techniques from my students while they’re learning broader programming tips from me. Like fine wine, instructors only get better with age. Every customer interaction [...]
