Under R version 2.4.0 (2006-08-30 r39024), sp fails CMD check following
the latest changes in methods.
The failures are in running examples and occur in CMD check:
> data(state)
> dd2dms(state.center$x)
Error in function (classes, fdef, mtable) :
unable to find an inherited method for function "initialize", for
signature "integer"
Offending code:
deg <- as(floor(dd), "integer")
After replacing by as.integer(floor(dd)), it fails on the local class
definition:
> dd2dms(state.center$x)
Error in function (classes, fdef, mtable) :
unable to find an inherited method for function "initialize", for
signature "DMS"
Installing sp, example("DMS-class") runs successfully interactively
(other examples do too).
The methods package is declared as Depends: in DESCRIPTION, and
import(methods) in NAMESPACE;
.onLoad <- function(lib, pkg) require(methods) is in the first R source
file in Collate: order.
Should the methods package be being invoked in some other way, is there a
reason why the installed package appears to run examples successfully that
fail under CMD check?
