Remark: if nothing works, an easy way out is to use the import wizard (File -> Import Data).The generated command can then be saved in a file and inspected or modified.

For someone who has been programming, SAS macros can feel very unintuitive.They are very much the tell-tale sign that the SAS language has been designedfor statisticians, not for developpers nor computer scientists.The easiest way to think reason about them is to think about the macro systemof the C preprocessor: SAS macro are mostly working as a text replacement tool,with some quirks.

Simplest macro:

Without variables, it is as simple as it gets.

With a loop

Variables, including loop variables, can be accessed with the &var. syntax.The loop syntax is close to for-loops in the usual languages.Documentation.

With parameters

As previously, we use the &var. syntax to access the content of a variable.

Using externally defined macro variables

Sas Macros Cheat Sheet

This is a bit more tricky. Assume you want to loop through the columns in a table.One way to do it is to define macro variables with convenient names, convenientmeaning indexable.

The data _null_ statement allow one to operate without creating a dataset which isthe default behaviour.The symput('varname', v) function assigns a value v to a variable called 'varname'.In the loop body, we then use the usual &var. syntax to access the loop variable value.However, we are not done: we need to further resolve Colname&i. to what we have definedin the data step.For this, we use the &&var1&var2. syntax, meaning 'first resolve var2 to its value, thenresolve the resulting expression.The process as I figure it out in my mind is the follwing:&&Colname&i. -> &&Colname1 -> &Colname1. -> 'ID'.

The sgplot procedure is fairly easy to use and flexible enough for most purposes.The only catch which has turned up to be utterly annoying is how the order of categoricalvariables is handled. I could not get it right even when sorting the data.The axescommand documentation is very useful.

Series for plotting lines

A simple example for theseriescommand.

A more complex example with groups, formats, custom colors and a legend.

Band for range of values

Sas

This one is very handy for plotting min - max values.

Vbar for vertical barplots.

Most of the options forvbarare valid forhbar.

Grouping data:

Density to visualize 1-D distributions

Sgplot'sdensityis very simple to use.

A useful alternative is proc univariate'shistogram statement.

Plotting maps is a bit more involved so I wrote a dedicated article:Plotting maps in SAS.

Proc formatcan be helpful in various cases beyond the obvious usage. Here are some samples.

Defining intervals for numerical values

Getting a summary about missing values

Writing the results of a query in a macro variable.

'Welcome and thank you for coming to my online page.

Let me introduce myself.

My name is David Franklin. I began an interest in programming back in 1981 and have continued this through to the present day. In 1985 I was introduced to a software package called SAS for the analysis and reporting of statistics for a government organization in New Zealand. 1990 saw big changes with the move to the United Kingdom where I had the chance to enter the Pharmaceutical sector as a SAS Analyst Programmer and later left to establish my own consultancy company based in London, England. From London I did work for several blue-chip pharmaceutical companies in the UK, Europe and the USA in the fields of Data Entry and Data Validation systems, Data Analysis and Presentation, both for internal and regulatory authorities. 2002 saw another big change when I moved my base to North-Eastern United States where I continue to contract out my experience and services to leading blue-chip companies throughout the world including North America, Europe and the South Pacific.

On my page you will find my resume, papers from presentations I have done, a useful SAS Cheat Sheet, a SAS Tip of the Month (and archive), some Useful SAS Notes and a full SAS code example of what SAS can do. I hope you find these useful and much more will be available in upcoming months so please visit regularly.

If you would like me to look at something you think I could help you with then please do not hesitate in contacting me at any time. My door is always open.'


Yours sincerely,
