R help - May 2013 - what does summary(polr(...)) really call?

dear R experts---how do I determine what summary(polr( y ~ x )) calls?
 it is not summary.lm(polr(y~x)) or summary.mlm or summary.glm, or
stats:::summary.lm or ...  in fact, none of the summary<esc> methods
seem to invoke what summary invokes.

advice, as always, appreciated.

regards,

/iaw

Look at methods("summary") to get  a list of the summary methods - it
includes summary.polr when MASS is loaded.  The starred ones are not
in any exported namespace, so "summary<esc>" (which I assume
means
name name completion in you UI) may not show them.  Use MASS:::summary.polr
to look at it.

MASS:::summary.polr because polr() returns a "polr" object.
