Hi, I tried to use the Croston function from the forecasting package 1.24<http://robjhyndman.com/software/forecasting> with the code below, but I get in return this message "*Error in decompose(ts(x[1L:wind], start = start(x), frequency = f), seasonal) : time series has no or less than 2 periods*". histValues <-ts(c(5,5,0,0,3,0,1,3,0,3,0,2,7,3,2,2,3,2,3,2,2,3,1,1,3,0,1,0,2,1,0,4,1,1,3,0,1),f=12,s=c(1998,1)) forecastValues <- croston(histValues, h=4, alpha=0.1) Does anyone know the causes and how to fix this problem? Thanks, Pedro Souto [[alternative HTML version deleted]]

The bug was corrected in v1.24 of the package uploaded to CRAN last April. Rob Hyndman
