Subject: [Rd] Using the lazy data mechanism
Message-ID: <20060204232842.TYLX17035.tomts5-srv.bellnexxia.net@JohnDesktop8300>

Dear list members,

I'm trying to use the lazy data mechanism with the car package, so far
without success. The data sets are in the source package's data subdirectory
in the form of compressed .rda files, and I added the directive LazyData:
yes to the package's DESCRIPTION file.

I suspect that the problem is that the package has no namespace, but I've
been unable to find a reference in the Writing R Extensions manual (nor
elsewhere) that suggests that this is necessary. Is there a place that I've
missed that describes the lazy data mechanism?

My system info:
