R plot arima fitted model with the original series

0 votes
I was initially using GRETL. But, when I tried doing the forecasting for the validation of ARIMA model, I got the fitted series in blue line and the original series in red line.

When I switched to R, I could not find any commands to do the same. I am using the ARIMA model from the forecast package.

Can someone help me with implementing it in R?

This question has many ways to answer, but here is a very, very basic answer. 

This is one of the examples provided in the help files for ARIMA in the forecast package:

fit <- arima(WWWusage,order=c(3,1,0))

Suppose you want the original series in red and the fitted series in blue:

plot(fit$x,col="red")
lines(fitted(fit),col="blue")

You can try out this commands and check the output!
