Hello there. I uses the following codes for the purpose of variable
selection.
> lmModel <- lm(y~.,data.frame(y=y, x=x))
> step <- stepAIC(lmModel, direction="both")
> step$anova
Stepwise Model Path
Analysis of Deviance Table
Initial Model:
y ~ x.Market.Price + x.Quantity + x.Country + x.Incoterm + x.Channel +
x.PaymentTerm
Final Model:
y ~ x.Quantity + x.Country + x.Incoterm + x.PaymentTerm
Step Df Deviance Resid. Df Resid. Dev AIC
1 1067 852257.2 7268.945
2 - x.Channel 1 127.9724 1068 852385.2 7267.108
3 - x.Market.Price 1 858.2886 1069 853243.5 7266.200
question:
Now, $anova list the final model only on the console. How do I retrieve the
variable names of final model (to be written into a text file later)?
Thanks.
