Ok - theat far I folow you. But how do I implement this?
I have now the following .onLoad() function:
,----
| .onLoad <- function(libname, pkgname) {
| setClass(
| "inDrak",
| representation(
| init = "SpatialGridDataFrame"
| ),
| contains = "simObj"
| )
| }
`----
in the file ./R/onLoad.R in my package.
Now how can I now use the setLoadFunction()? I tried to simply put the
setClass in the setLoadFunction() as follow into the ./R/onLoad.R file:
,----
| setLoadFunction( function(libname, pkgname) {
| setClass(
| "inDrak",
| representation(
| init = "SpatialGridDataFrame"
| ),
| contains = "simObj"
| )
| }
`----
but this did not work.
So what do I have to do with it? I only find very few examples using
setLoadFunction().
