I am trying to fit an ARIMA model to some time series data, I have used differencing to make the data stationary.

dailyibm is the data I am using, could someone please help out in identifying the coding as I can't seem to identify the problem 

many thanks

> fit.ma <- arima.sim(dailyibm - mean(dailyibm), model=list(order=c(0,1,0)),n = 3333)

Error in inherits(x, "data.frame") : couldn't find function "rand.gen"
