Hi, A few weeks back I used the following command: accuracy(train,test) where train and test are training and test data respectively. Last night I updated R and the forecast package and used the same command and I got error. After trying a little I used the following command accuracy(train,test[1:30]) and it worked. (I was checking the accuracy of 30 forecasted values). Is there some change in the forecast package or did I do something wrong? regards Leo

Thanks. Could be the following reason given in the changelog. " accuracy() can now figure out overlapping times for x and f." best regards Leo On Mon, Dec 17, 2012 at 10:11 AM, Jeff Newmiller
