Well, the thing to note is that
	summary (RegModel.1)
is something different from
	print (RegModel.1)
. If you try the latter in the R console, you will see the same result as in 
the object viewer. If you do
	rm1.summary <- summary (RegModel.1)
and you view that object, you will see the result you have been expecting.

So it's not really a bug. But perhaps it would indeed be useful to (try to) 
show the summary for objects in the object viewer, in addition to printing 
them. I'll add it to the TODO list.

(The object viewer is one of the oldest portions of rkward, and has seen only 
very few changes since it's inception in 2004. I guess it could need some 
attention...).

Thomas
