R help - Sep 2009 - What are the return values of aov?

Hi,

I don't quite understand what are the return values of aov. I know
that it has 'coefficients'. But I need to know what all the other
return values are. Can somebody let me know how to figure them?

Value:

     An object of class 'c("aov", "lm")' or for
multiple responses of
     class 'c("maov", "aov", "mlm",
"lm")' or for multiple error strata
     of class '"aovlist"'.  There are 'print' and
'summary' methods
     available for these.


Regards,
Peng

Hi Peng ,
I am not sure I understood your question.
Are you asking what the "ss" and "p values" and so on mean ?

Hi,

I get the following variables. Instead of guessing what they mean, is
there a centralized location in R help() that describes their meaning
and usage?
> names(afit)
 [1] "coefficients"  "residuals"     "effects"    
"rank"
 [5] "fitted.values" "assign"        "qr"         
"df.residual"
 [9] "contrasts"     "xlevels"       "call"       
"terms"
[13] "model"
