Hi there!

I am considering to port a SAS application to R and I would like to hear your opinion if you think this is possible and worthwhile. SAS is mainly used to do data management and then to do some aggregations and simple computations on the data and to output a modified data set. The main problem I see is the size of the data file. As I have no access to SAS yet I cannot give real details but the SAS data file is about 7 gigabytes large. (It's only the basic SAS system without any additional modules)

What do you think, would a port to R be possible with reasonable effort? Is R able to handle that size of data? Or is R prepared to work together with some database system?

Thanks for your thoughts!

Best regards,
  Werner
