[R] Problem with ploting fitted values

[matys]

Hello!
I have such a problem...
Estimated a model based on common data (you can find it in R library), and I
wanted to plot the orginal values with the estimated one. Unfortunately I
can only see the original values.

Below is the code with data library:

/
library(forecast) 
data(AirPassengers)
AP <- AirPassengers
class(AP)
start(AP)
end(AP)
frequency(AP)
lgAP <- log(AP)
t<-2:length(AP)

APsL<-log(ts(lgAP, start=1949, frequency=12))
final<-(ts.intersect(lgAP,lgAPlag=lag(lgAP,-1), t=t,
		sin12 =  sin(2*pi*t/12), cos12 = cos(2*pi*t/12),dframe=TRUE)) 

summary(AIRlm <- lm(lgAP ~ lgAPlag + t + sin12 + cos12, data=final))

plot(lgAP, main="Log of Air Passengers",type="l", col=4, lty=2, lwd=2)
lines(t, AIRlm$fitted, col=2, lwd=2)
legend("topleft", legend=c("data", "fitted"), lty=c(2,1), col=c(4,2))
/

As you can see the "lines" command doesn't work.
I'm open to your suggestions and would be very grateful for your help.
