Error in .cbind.ts(list(...), .makeNamesTs(...), dframe = FALSE, union = TRUE) :

Hi there ,

I am trying to forecast for a holdout data set with a 'h=21' value which is throwing me the error stated below .

Error in .cbind.ts(list(...), .makeNamesTs(...), dframe = FALSE, union = TRUE) : 
  non-time series not of the correct length

My code runs fine for until a h value of 19 but nothing beyond that value .

Pasting my code below

ArimafcastA <- forecast(, h=21)

VecA2 <- cbind(DataTest_A,ArimafcastA)

Can someone tell me what I am doing wrong here ?


Could you please turn this into a self-contained reprex (short for reproducible example)? It will help us help you if we can be sure we're all working with/looking at the same stuff.


If you've never heard of a reprex before, you might want to start by reading the help page. The reprex dos and don'ts are also useful.

What to do if you run into clipboard problems

If you run into problems with access to your clipboard, you can specify an outfile for the reprex, and then copy and paste the contents into the forum.

reprex::reprex(input = "fruits_stringdist.R", outfile = "")

For pointers specific to the community site, check out the reprex FAQ.
