Spencer, I find some of your comments/questions on R packages, extremely basic.
(Sorry, if that sounds condescending, but I'm wondering if your
comments/questions would be better R-package-devel?).

You need to look at the imports and depends fields.
(As stated in my previous post).

The *first* package on the Ecfun imports list, is fda, which is *your*
package (technically, contributor), and it has a dependency on the
Matrix package.

I'd recommend you read the documentation on writing R packages, and on
how package namespaces are handled.
