I've never used it, but it looks like the package 'foreign'  can read (some
types of?) SPSS data and import into R:

http://cran.r-project.org/web/packages/foreign/index.html

If the data is amenable to become a data.table (ie. it's data.frame -like)
you can convert it "in the usual way."

Note that in the development version of data.table, Arun has implemented a
setDT method which converts a data.frame to a data.table without making a
copy, which might be helpful to you if your data.frame eats up enough RAM.

HTH,
-steve
