Although you commented earlier on the quality of the R documentation, you
are asking a question in your subject line that is answered both in the FAQ
and in the R for Windows FAQ.  As the answer depends on the version of R in
use, and Maindonald's text is (well) out of date, you will need to read the
FAQ for your version of R (which the FAQ asks that you report).

Please also read the section of the FAQ on bugs, and note both the
information we need to help with problems and the advice not to report
your guess at the answer without the facts.

Do check that the version of foreign you are using is compatible
with the version of R you are using, preferably by compiling it yourself.
Using incompatible versions will lead to crashes.

You might also like to consider following the advice in the R Data
Import/Export manual to export the data from SPSS in a non-proprietary
format.  It is there for good reasons, one of which is known reliability.
