[R] stepAIC: plot predicted versus observed

[sergeetienneparent]

I figured out how to call coefficients and R² from the summary.

-----------------
fit<-lm(...) #multiple regression function
stepComp <- stepAIC(fit, direction="both")
summary(stepComp)$coef[1,1] #call first coefficient
summary(stepComp)$coef[1,2] #call Std. Error of first coefficient
summary(stepComp)$coef[2,1] #call second coefficient
#... so on...
#And the R² can be called by
summary(stepComp)$adj.r.squared #call adjusted R²
summary(stepComp)$r.squared #call multiple R²
