Subject: setMethod and contains not saving
Sorry if this is a duplicate....
I'm having the following problem saving methods which are subclasses of other
objects. Is there a workaround. The problem is that the R file that
triggers this bug is several meg, and I'd like to load from a RData file.
This works
> setClass('foo')
[1] "foo"
> setMethod('$', 'foo', function(x,name) x)
[1] "$"
> showMethods('$')
Function "$":
x = "ANY"
x = "foo"
> q()
Save workspace image? [y/n/c]: y
(restart)
> showMethods('$')
Function "$":
x = "ANY"
x = "foo"
This doesn't ....
> setClass('bar', contains='foo')
[1] "bar"
> setMethod('$', 'bar', function(x,name)x)
[1] "$"
> showMethods('$')
Function "$":
x = "ANY"
x = "foo"
x = "bar"
> q()
Save workspace image? [y/n/c]: y
(restart)
> showMethods('$')
Function "$":
x = "ANY"
