[R] Rsquared in summary(lm)

[wouter buytaert]

Hello,

I'm doing some linear regression:

>lm<-lm(osas~alp,data)
>summary(lm)

However, the Rsquared in the output of summary() is not the same as the
"standard" Rsquared calculated by spreadsheets, and outlined in
statistical guidebooks, being SSR/SSTO. The output says "multiple
Rsquared", but it is no multiple regression...

What's the difference?

Thanks,

Wouter Buytaert
