SAS codes are ugly, I have also been looking for an automatic software to convert SAS to R, however, haven’t got anything. So far I have to manually convert the codes, but it is a pain. Please share with us if you find some, thanks.

@Michael: Thanks for proposing the PMML approach. I will have a look at the SAS-to-PMML tool. Thanks for all the links.

@John: For interpreting SAS/Base code, the only tool I know is WPS. It is not free but much cheaper than a SAS licence. From SAS to PMML you can look at the link from Michael. I have never used S, so I can’t help you for that.

Are there any opensource stats programs that will interpret my old SAS/base code. Also is it possible to convert SAS language to PMML to S language? Or just use PMML in R?

I highly recommend to take a closer look at the Predictive Model Markup Language (PMML) standard which is supported by most commercial vendors as well as open source tools. Open standards are the way to go, if you want to keep your options open and have more flexibility to choose a best-of-breed solution. PMML bridges the gap to production deployment and integration of predictive models, e.g., you can deploy your models on the Amazon EC2 cloud with Zementis http://www.zementis.com

For SAS, only Enterprise Miner currently supports PMML export. However, there seems to be a free tool that converts Base SAS to PMML, available for download at http://www.latentview.com/sas-2-pmml.html

To learn more about PMML, please join the PMML discussion group on LinkedIn with links to various resources, tools that support PMML, and more:

@Shane: Thanks for your comment. I’m now trying WPS, which can read and interpret SAS code (with a much cheaper license price). I will blog about that soon.

I dont think most people would replace SAS with Java programming… PostgreSQL/MySQL in combination with R or RapidMiner would be ok though.

@Jay: Thanks for your input. I agree with you, that the platform/language should be chosen in advance. But it is often fixed by the client. And, in the consulting area, the client changes very often.

Sandro is right. Even though SAS is a powerful platform for analytics, not every client can afford it or need it. Also many of the practical analytics problems can be solved with freely available tools (open source or otherwise). It is just a matter of selecting right tool for the budget and requirement. As far as the conversion from SAS to Java, I have not faced such problems but prefer to write application in Java platform than to convert. It is just my preference.

@Haltux: Thanks for sharing your opinion.

I believe that the current success of Java is in big part due to the applets (but I may be wrong).

Regarding the reimplementation, I agree, one should perhaps use an existing tool such as WEKA.
