I am trying to use auto.arima to fit a univariate time series and do forecast.
This is an imaginary data on monthly outcomes of 2 years and I want to forecast
the outcome for next 12 months of next year.
data Data1;
input RR;
datalines;

run;
I successfully took this data into R and used the auto.arima codes but am
getting the following error:
fit <- auto.arima(Data1)
------------------------------------------------------------------------------------------------------------
Error in model.frame.default(formula = x ~ 1, drop.unused.levels = TRUE) :
invalid type (list) for variable 'x'
------------------------------------------------------------------------------------------------------------
Please help.
Thanks,
Ruchi
