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 […]

As a kid, I was always intrigued with UFO sightings and I guess I’m still a little that way … therefore how could I not jump at the opportunity to explore some UFO sightings data! I guess “UFO” doesn’t necessarily imply that something is an alien space ship – just […]

It was very disappointed that there is only one built-in method to calculate covariance in Base SAS: that’s in PROC CORR (while you can also do it in SAS/IML, of course): The following is a quick-and-dirty way to get a function like %COV: %macro COV(data, var1,var2); %local _cov; %let rc = %sysfunc(dosubl(%str( ods output […]
I didn’t play with SAS/IML for a while. I call it back when I need to read some R format data. Technically, .Rdata is not a data format. It’s rather a big container to hold bunch of R objects: In this example, when a .Rdata is loaded, 3 objects are included where ‘data’(the ‘real’ data) […]
In recent releases of SAS, you can use Output Delivery System graphics or ‘ODS graphics on’ to produce nice graphical output for most of the analytic procedures. These default graphs are nice, but when you want your graphs to look “a certain way” SAS also lets you create your own custom graphs! […]
