I downloaded data from 

 

http://www.hcp.med.harvard.edu/ncs/

 

 

Which provides data in DTA  (STATA), XPT (SAS), and POR (SPSS) formats all
of which I have tried to read with the foreign package but I am not able to
load any of them. I have 2 gb of RAM, but R crashes when the memory gets
just over 1 GB. I am using Windows version 2.1.1. The size of the DTA file
is 48 MB; the xpt file is 188 MB.

 

I would appreciate any suggestion you have about how to read this data with
R.

 

Thanks,

 

Jim Hurd
