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. -- View this message in context: http://r.789695.n4.nabble.com/Problem-with-ploting-fitted-values-tp4192218p4192218.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
