Hi,
I have used the instruction aov in the following manner:
res <- aov(qwe ~ asd)
when I typed "res" I get:
_________
Call:
aov(formula = qwe ~ asd)
Terms:
asd Residuals
Sum of Squares 0.0708704 0.5255957
Deg. of Freedom 1 8
Residual standard error: 0.2563191
Estimated effects may be unbalanced

I need to access the value of the Sum of Squares (i.e. I want
another variable to be equal to it, e.g myvar <- Sum.of.Squares) .
I tried names(res) to see which values are accessible, but I
couldn't find the Sum of Squares. I had a similar problem when I
tried to access the p.value which can be readily SEEN using
summary(res).
In general, is there an easy way to access the values generated by
an R function?
When you typed "res", the interpreter determined that it was of type
"aov" and dispatched it to the print method for objects of that class.
The list of print methods is accessed with:
methods(print) and it's a long list. print.aov is asterisked so you
either need to look at the function with:
getAnywhere(print.aov)
....or perhaps more directly assign summary(res) to an object and
access its SS values.
