There seems to be an error in the summary() function when applied to "ts" class objects. The results of a call to summary( ), on the R "ts" data set USAccDeaths , reports the wrong value for Max. The value reported by the summary function is 11320. The max( ) function returns the correct value 11317, the July 1993 value. Coercing the data to a data.frame and calling summary returns the correct max value. A search of R -help found a post in 2007 that menti...

Hello, I have just completed first experiments in using R, especially creating and using ARIMA models, e.g. # create a model as in example(arima) fit <- arima(USAccDeaths, order = c(1,1,1),seasonal = list(order=c(1,1,1))) # use the model to generate a prediction dp<-predict(fit, n.ahead = 24) plot(dp$pred) # view the prediction Now I created a combined chart of the original and predicted values. I tried it like this: dvs <- c(as.vector(USAccDeaths),as....

I don't understand where is my problem. I tried the problem suggested by Prof. Brian Ripley data(USAccDeaths, package="ts") and it worked. So this is not a machine or configuration problem.

Can someone enlighten me on why the following doesn't work? setwd('C:/Temp/R') d <- rep(1:53,2) (s <- ts(d, frequency=53, start=c(2000,10))) n <- length(s) k <- n%/%3 for(i in (n-k):n) { st <- c(start(s)[1] + (start(s)[2] + i)%/%frequency(s), (start(s)[2] + i) %% frequency(s)) ed <- c(start(s)[1] +

...is this: is it ok to use the same t in predict function or should my newxreg contain 99 values in order to properly predict the 99th value for LakeHuron? Another problem is that i don't receive the 99th value on the screen, as i should (running the example in ?predict > (fit <- arima(USAccDeaths, order = c(0,1,1), + seasonal = list(order=c(0,1,1)))) > predict(fit, n.ahead = 6) gives me on the screen the predicted values, so i think I must be doing something wrong) 2. If i have ts for 3 regions of the country, is it ok to model each one independent of each other ? or is...
