+Chris Hemedinger is the Director of SAS User Engagement, which includes our SAS Communities and SAS User Groups. Since 1993, Chris has worked for SAS as an author, a software developer, an R&D manager and a consultant. Inexplicably, Chris is still coasting on the limited fame he earned as an author of SAS For Dummies.
We ship many sample data sets with SAS products. By using well-understood sample data sets, we can teach concepts or show off product features without distracting the audience/students with data collection or prep. At least, that's the way it's supposed to work. But occasionally the sample data can cause a
It's been a well-known limitation for a long time. When you connect to a SAS session using SAS Enterprise Guide, shell commands (including X command, SYSTASK, and FILENAME PIPE) are off-limits because the default SAS invocation disables them. It does this by including -NOXCMD as a command-line option. This makes
At least, that's according to my colleague, Rick Wicklin. In a recent blog post, Rick points out that estimating popularity based on results of Google searches is a bad idea. Well, that just disqualified my claim that PROC REPORT is more popular than PROC TABULATE, as measured via a GoogleFight.
While talking to SAS users in Australia earlier this month, I often demonstrated the capabilities of the new Map Chart task in SAS Enterprise Guide 4.3. Creating map charts has never been easier: select your map data source, then select your response data source, and click Run. Voila! You've got
Was the SAS Insight Series in New Zealand and Australia a prelude to the Rugby World Cup? Perhaps it was, even if you cannot find it on the list of official events. But consider these coincidences: Like the Rugby World Cup, my trip was also sponsored by MasterCard. (Okay...not
I'm currently enjoying the Australian "winter" as I travel around the region talking to SAS customers for the SAS Insight Series. It just so happens that I was in Perth, Western Australia for Australia's Census Night. Because I was in the country on this special day, I was compelled
One of the great innovations with SAS 9.3 is the focus on ODS statistical graphics. "Wait a minute," you're thinking, "weren't ODS graphics added in SAS 9.2?" Yes, that's true. But with SAS 9.3 there is even more capability: more analytical SAS procedures support the graphs, and there are more
I feel privileged to have been invited back to meet with SAS customers throughout New Zealand and Australia. I also feel lucky to escape the North Carolina summer (with temperatures trending in the 90s Fahrenheit) in exchange for the "winter" weather Down Under. For a good chunk of August, I'll
Rick Wicklin created his own list of Five Interface and Graphics Features that Everyone Can Use. It's a very good summary of what you'll immediately notice when you use analytics procedures in SAS display manager: cool graphs turned on by default. For SAS Enterprise Guide users, you won't see such
Alison posted the Top 10 Reasons you should care about SAS 9.3. It's a bit tongue-in-cheek, but it reflects just a sample of the thousands of features and tweaks that you'll see in this new release. Even with SAS 9.2, I was nowhere near exhausting my backlog of blog topics...but
It seems like such a simple problem: how can you reliably compute the age of someone or something? Susan lamented the subtle issues using the YRDIF function exactly 1.0356164384 years ago. Sure, you could write your own function for calculating such things, as I suggested 0.1753424658 years ago. Or you
SAS Enterprise Guide sets values for several useful SAS macro variables when it connects to a SAS session, including one macro variable, &_CLIENTPROJECTPATH, that contains the name and path of the current SAS Enterprise Guide project file. (To learn about this and other macro variables that SAS Enterprise Guide assigns,
As I write this, SAS 9.3 has not yet been "shipped", but its release is imminent. I've already heard many questions about how SAS Enterprise Guide works with the new version, so I decided to write this "Frequently-soon-to-be-asked questions" document to help sort it out. What version of SAS Enterprise
The recent issue of InformationWeek features a Q&A session with Ken Thompson, one of the creators of the Unix operating system. (He collaborated with Dennis Ritchie, of C language fame. Since much of SAS is written in C, I daresay there are a few copies of K&R around here.) One
About a year ago (wow, has it been that long?), I posted an example program that lets you report on the contents of a SAS information map. Using my example, you can see the data items, filters, and folder structure within a given information map. Last week a reader posted
We sometimes take it for granted, but the concept of the "SAS library" is just about one of the most awesome aspects of The SAS System. You can give your library a name (a library reference, or libref), tell the system how to get to your data (options on a
SAS-based processes are critical to many organizations, but sometimes the trickiest part of your job falls into one or both of these activities: Getting stuff from the outside world "into" SAS. (Once it's in SAS, as many of you know, the world is your oyster.) Getting the output of your
Sometime very recently, probably while you weren't looking, I changed jobs at SAS (yes, again). This time it's a bigger change for me, because I'm no longer part of the SAS R&D organization, where I've worked for nearly 14 years. Instead, I'm part of the team known internally as Professional
SAS Enterprise Guide has about 150 options that you can customize in the Tools->Options window. With each release, the development team adds a few more options that have been asked for by customers, and they rarely decommission any existing options. It's getting quite crowded on some of those options windows!
I hope that the following statement is not too controversial...but here it goes: Microsoft Excel is not a database system. That is, I know that people do use it as a database, but it's not an application that supports the rigor and discipline of managing data in the same way
It's a simple task to use SAS to compute the number of weekdays between two dates. You can use the INTCK function with the WEEKDAY interval to come up with that number. diff = intck('WEEKDAY', start_date, end_date); If you want to compute the number of working days between two dates,
SAS Enterprise Guide is best known as an interactive interface to SAS, but did you know that you can use it to run batch-style programs as well? SAS Enterprise Guide has always offered an automation object model, which allows you to use scripting languages (such as VBScript or Windows PowerShell)
Greg Nelson and Neil Howard presented a lunchtime keynote talk at SAS Global Forum, and they produced this video, "Revenge of the Semi-Colon People", to go along with it. The video features many people from the SAS community, including customers and SAS employees. Watch it and see if you know
When I encounter an ERROR, WARNING, or NOTE in my SAS log that I don't understand, my first recourse is to ask my friend (we'll call him "Google") what it could mean. I copy the entire message (or at least 5 or 6 consecutive words from it) into the search
This morning I delivered a talk to visiting high school students at the SAS campus. The topic: using SAS to analyze Twitter content. Being teenagers, high school students are well familiar with Twitter. But this batch of students was also very familiar with SAS, as they all have taken SAS
Yesterday I was in the Big Room for the rehearsal of the Technology Connection, the part of SAS Global Forum where SAS shows off its wares: what's been released recently and what's coming. I believe that customers are going to love what they see. And just about every product that
While talking to fellow SAS users at SAS Global Forum 2011 this week, I'll be discussing how SAS programmers can "play" with social media data that they can access on Facebook and Twitter. I always refer people to my blog for more information, and so I've prepared this blog post
This morning Rick Wicklin announced his (hostile?, nah...) takeover of the technical blog space at SAS. I'll admit that it took me by surprise when I awoke in Siberia this morning. It's so cold here; I can't feel my fingers as I type. This is probably a punishment for the
"Twitter, thou art nought but data." So sayeth the SAS programmer. Many data analysts now recognize Twitter for what it is: a tremendous source of data covering almost any topic, from Justin Bieber's hair to political uprisings to technical conferences to company brands. SAS offers sophisticated solutions to harness this
Many SAS users love "undocumented features" within SAS software that they have found or heard about. Sometimes they can be really useful, and the fact that they are undocumented adds to the mystique. Some users have written entire conference papers on the subject. After 35 years of evolution, SAS contains
