The FAQ Q8.1 does recommend that summary() methods do not print themselves
but returned a classed object to be printed.
What doItAndPrint does is to capture the result of an explicit print, so
it will only work for summary methods that follow that recommendation.
I do think doItAndPrint should be capturing all the output from a function
via sink(), and not just the print of the final result.

Dear list member,
John Fox proposed to me posting this problem to R-Help:
I have written a function suited for Rcmdr and included this in a R-file
located in Rcmdr/etc as well as an augmented `Rcmdr-menus.txt'.
Now, I am faced with the following problem:
method show() of a S4-class object works flawlessly, that is `doItAndPrint'
works flawlessly and its output is returned correctly into the Rcmdr-Window.
However, by using method summary() for the same S4-class object fails, in
the sense that the output is *not* printed in the Rcmdr window, but into the
R Console. The summary()-method contains cat() and slots of the S4-class
objects only.
My question is: How can it be achieved that method summary() of S4 objects
is printed in the RCmdr window and why, in the first instance, does it fail
to do so by using `doItAndPrint'.
Any help or pointer is much appreciated,
Best Regards
Bernhard
