R help - Sep 2013 - Is R able to fit and forecast arima models using daily time series?

Hello everyone,

I have been struggling quite a bit with R whenever I try to fit ARMA or
ARIMA models and produce forecasts for datasets containing daily
observations.

Can somebody tell me whether R can handle daily time series or not? I have
the impresion that R cannot fit nor produce forecasts for datasets with
daily historical observations but I need to make sure that this is actually
the case.

Any help and/or guidance will be greatly appreciated,

Best regards,

Paul

Hello,

R is able to handle daily time series. A problem arises when you have to
deal with leap years. "zoo" is able to manage 365 or 366 days a year,
while "ts" is not able to do that, . But as far as I read, most of
ARMA,
ARIMA or SARIMA works with "ts", not with "zoo". Maybe some
else might
provide you more help.

Regards,
Pascal
