I downloaded data from  


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.
