makeActiveBinding( 'myAB', function( x) if( missing( x)) get( 'myABguts', env=.GlobalEnv) else assign( 'myABguts', x,
.GlobalEnv),
exists( 'myAB')
which appeared to return absolutely nothing-- not even a
missing or a null. The problem, of course, is that 'myABguts' doesn't exist yet; what seems to happen, though, is that the failure to 'get' causes a *messageless* error inside the active binding function. Is this intended?

What I get is this:
> exists( 'myAB')
Error in get(x, envir, mode, inherits) : variable "myABguts" was not found
[MVB] Hmmm, yes, this morning that's exactly what I get too. I was running this on a different machine (also R2.0.1 under Windows XP) when I repeatedly got the messageless error which prompted my question. I'll see whether I can re-reproduce it on that system. Thanks Mark
