that is likely the solution to my problem, but I don't understand how I
can use it and I can't find the example in the Rcpp package (I did grep
for setLoadAtion on the whole source package of Rcpp, but nothing came up with
). Could you
please provide me a link (or the filename) where

The basic tool is setLoadActions(), which takes a function definition, with the
package's namespace as its argument. Read ?setLoadActions
There is no such thing as setLoadFunction, as far as the standard code in R.
While you haven't defined didn't work, an off-the-top-of-the-head idea would
Hi
I am writing a package in which I define a new class in the .onLoad()
hook:
,
| .onLoad - function(libname, pkgname) {
| setClass(
| inDrak,
| representation(
| init = SpatialGridDataFrame
| ),
| contains = simObj
| )
| }
`
Don't use .onLoad() to set class (or other nontrivial) information at load
time. Use setLoadActions(), which was created exactly to get around the
limitations of .onLoad().
For an example, see the Rcpp package, which uses this to set up load-time C++
linkages.
