Hi all,
referring to the function package guide section 4.3.2, "Run-time limits
and defaults". This should apply to int(egers) and scalar(s), and I
think for integers I have used that successfully at least for the upper
and lower limits (not sure about the defaults).
But for general scalars, I'm having problems cooking up a working
example - so is there a package out there that uses this feature?
Or going back to integers, a package that does run-time defaults, not
just limits?
thanks
sven

Any ideas about which packages do this? Jack, some of your recent
updates perhaps?

OK, off-list, Jack indeed pointed me to his ZivotAndrews package which
does this default thing with integers. Thanks!
For general scalars, I'm having no luck, though. I'm attaching a
barebones example which doesn't work for me - meaning that its default
is defined as 2, but that's not shown. (The corresponding variant with
an int argument works OK.)
(Disregard the included private function initial_defaults, it's not used
there.)
An unrelated extra GUI problem: When executing this package, there is a
"+" button at the right, to create a new scalar variable. When I click
it, I get a formula entry window. Then I just enter (wrongly) a new name
(say "hu") but no formula. I get an empty error window with no message
and a close button. (Apparently in the background "hu" is created and
initialized as usual with NA, that's not the issue.)
thanks
