[R] How to specify search order for require()

[Luke Tierney]

As of 1.4 (I believe) packages loaded by a require in the package
source, as oopsed to .First.lib, are loaded after the package that
calls require.  This was done in part to allow packages to
require(methods) and then use functions defined in methods within the
package body.

Hopefully R 1.6 will add a name space mechanism that will provide much
finer control over package dependencies; some information on how that
might work along with a draft implementation is available off the
developer page developer.r-project.org or at
http://www.stat.umn.edu/~luke/R/namespaces/morenames.html.

But I want the package being loaded by .First.lib using library.dynam("mypackage",pkb,lib) to be higher in the search order than the two required packages, because I want to have a couple of functions from the two required packages overridden.  What is the best way to do that?  Thanks in advance -Frank
