[R] SAS vs. R in web application

[Frank E Harrell Jr]

Carlos,

The last time I checked the SAS license for web use was $25,000 per 
year.  R costs $0 per century.  Still interested in SAS?

Not sure about your question about 'DOS window'.  R on a web server 
interacts with your browser and doesn't open other windows.  There are 
several online demos of R on web servers.

Would this option require a multi-user SAS license? (I know, I should check with SAS Institute, but I thought I'd ask anyway. Someone in the list may have done something similar).
