Dear R Developers:
What is the proper log(likelihood) for 'factanal'? I believe it
should be something like the following:
(-n/2)*(k*(log(2*pi)+1)+log(det(S)))
or without k*(log(2*pi)-1):
(-n/2)*log(det(S)),
where n = the number of (multivariate) observations.

Hi,
one thing I haven't been able to figure out from R-exts is how to
interrupt a calculation running inside an embedded R. C code inside R
calls R_CheckUserInterrupt() intermittently to check for interrupts,
but how does my GUI tell R that the user wants it interrupted?

I'm wrestling with the same issues, so this is the blind leading the
blind, but that usually prompts someone knowledgeable to say something
useful.

Since compiling R 2.5.0 from source on my Mac (PowerBook) I've noticed
some strange behavior when plotting. I'm not sure if it's a problem
with my setup/compilation because I feel like a problem as basic as
this one would have been reported already. I'm running R with X11 and
R was built with gcc
