I am just starting to learn R, and I'm struggling with a lot of the basic
stuff. The online documentation is generally good, but I have been unable to
find the answer for my problem this time.
I am running linear regression on a particular set of data and plotting it.
I've got the regression line plotted and everything is fine so far, except
for one thing: I want to display the SSE from the regression and I don't
know how to access it. In my script I have:
model <- lm(y~x)
and I was able to get the r^2 value that I wanted with:
summary(model)$r.squared
But I don't know how to get the SSE. When I print the summary(aov(model)) I
get the following:
Df Sum Sq Mean Sq F value Pr(>F)
x 1 1793928 1793928 67.463 3.447e-11 ***
Residuals 56 1489118 26591
---
Signif. codes: 0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1
So it's there (I can see it!) but how do I get to it? Any help would be much
appreciated.
Thanks,
Kelly
