Hello R People:

Here's the Saturday night goofy question.  I would like to see the
code for TukeyHSD function and I tried the following:
A single object matching ?TukeyHSD? was found
It was found in the following places
  package:stats
  namespace:stats
with value

function (x, which, ordered = FALSE, conf.level = 0.95, ...)
UseMethod("TukeyHSD")
<bytecode: 0x0000000005d22f90>
<environment: namespace:stats>
function (x, which, ordered = FALSE, conf.level = 0.95, ...)
UseMethod("TukeyHSD")
<bytecode: 0x0000000005d22f90>
<environment: namespace:stats>
I thought that the 3 colon would take care of matters.  What am I
missing, please?

Thanks yet again,
Sincerely,
Erin

TukeyHSD is not the real function name. It's a generic function and  
you need to look at the code for whichever function of the possibly  
multiple TukeyHSD's you are interested in.

?methods
methods(TukeyHSD)

Hi Erin,

What you're missing is that the TukeyHSD function is generic. There seems
to be only one method for it, namely TukeyHSD.aov.  Try typing:

     methods(TukeyHSD)

On my system if I type

     TukeyHSD.aov

I see a splendiferous amount of lovely --- and (mirabile dictu!) reasonably
comprehensible-looking --- code.

     cheers,

         Rolf
