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.
