Dear Developers,
A lot has been changed in the R12.0 with respect to behavior of "environment"
subclasses. Many thanks for that.
One small irregularity, though; new.env does not allow the parent to be from S4
subclass.
> setClass("myenv", contains="environment")
[1] "myenv"
> new.env(parent=new("myenv"))
Error in new.env(parent = new("myenv")) : 'enclos' must be an environment
I wonder if this is a "planed" behavior.
The use of .xData slot obviously works:
> new.env(parent=new("myenv")@.xData)
<environment: 063bb9e8>
>
Thanks,
Vitaly.
