You already know about the ANOVA table used to describe a multiple regression.
we might build the table
which we can read off almost directly from the SPLUS output

Analysis of Variance Table
Response: logoz
Terms added sequentially (first to last)
Df Sum of Sq Mean Sq F Value Pr(F)
rad 1 17.15661 17.15661 66.3508 0.0000000000
temp 1 33.66815 33.66815 130.2069 0.0000000000

Residuals 107 27.66744 0.25857
This sort of ANOVA table will be useful when we build and assess ANOVA models, but ANOVA is not merely this table.
