[R] ANOVA

Dear all,
I have a problem regarding the anova() output. When I apply it to a
single regression model, I do not understand how the values
corresponding to the F statistics are obtained by the software. I
believe that they are computed using differences between residual sums
of squares of sequential models obtained from the imputed one (removing
one independent variable at a time). I have tried to do the computations
by hand, but my figures do not match R's.
I would very much appreciate it if anyone could shed light on this.
Thank you in advance,
