Doing more with nbsp

A few weeks ago I wrote an article on using the non breaking space character to prevent stripping of leading and trailing blanks in a string.   Since then, I have discovered a few more instances where the nbsp can be a useful tool for creating graphs. One such instance came up last week

SUG Road Trip! WUSS in Long Beach, CA

It’s that time of year again! The leaves are turning, the days are getting shorter, and all across the country, SAS users are getting ready for the annual users group conferences. To get people excited about the upcoming events, I’ll be hitting the road—metaphorically, at least—and virtually visiting each of

Construct a magic square of any size

Magic squares are cool. Algorithms that create magic squares are even cooler. You probably remember magic squares from your childhood: they are n x n matrices that contain the numbers 1,2,...,n2 and for which the row sum, column sum, and the sum of both diagonals are the same value. There are many

The MOD function and negative values

When I studied math in school, I learned that the expression a (mod n) is always an integer between 0 and q – 1 for integer values of a and q. It's a nice convention, but SAS and many other computer languages allow the result to be negative if a (or q) is

How about some pie?

Pie charts have been the subject of some criticism when they are used to compare measures across multiple categories.  It is generally accepted that comparison of magnitudes represented as angular measures from varying baselines is not effective. However here are some use cases where a pie chart does quite well. When it comes

Value of SAS

As a trainer for SAS Education Australia and chairperson of the local SAS User Group, QUEST (Queensland Users Exploring SAS Technology) , I meet many new SAS users over the years. In July 2011, I met Kim MacKenzie, a lecturer at Queensland University of Technology (QUT), Brisbane, Australia at an Enterprise

Compact Scatter Plot Matrix

The Scatter Plot Matrix is a great tool that provides a quick visual of potential associations between variables.  This may provide the analyst some hints on how to proceed with the analysis. Matrix of lab values for liver function tests are commonly used in clinical research.  The SGSCATTER procedure provides an easy way

SAS loves math ... of course

Every summer, SAS hires interns from colleges across the US. Now, I've worked at other organizations, and I've worked with interns before. These guys are brilliant - the rising stars of industry. This year, one of the summer interns is Dylan Sweetwood. He'll be returning to Stanford in the fall,

Non-breaking space

Forest plots come in many flavors.   An example of a Forest plot using GTL is available on the SAS support web site.  Simple forest plots can also be created using SGPLOT procedure by using the SCATTER statement with MARKERCHAR to display data aligned with the plot by study names. One issue
