Dear Sir/Madam,

 

I have an old R-code using R-metrics functions that worked quite well
under R2.7.

 

Having updated R to 2.8 and all packages as well, the same (!) code does
not work any more. The main problem that I have is that R keeps
complaining that the timeSeries object does not contain any data which
is not true. You will find one example below. Can you help? Thank you.

 

Yours truly,

 

Wing Lon Ng
