If anyone wants to see a prime example of how inefficient it is to program in SAS, take a look at the SAS programs provided by the US Agency for Healthcare Research and Quality for risk adjusting and reporting for hospital outcomes at http://www.qualityindicators.ahrq.gov/software.htm . ?The PSSASP3.SAS program is a prime example. ?Look at how you do a vector product in the SAS macro language to evaluate predictions from a logistic regression model. ?I estimate that using R would easily cut the programming time of this set of programs by a factor of 4.
