[R] Best datatype for time-series with irregular ocurrencies

[jmoreira@fe.up.pt]

Hello,

Does someone has experience working with time-series where the ocurrencies do 
not happen at regular time spaces? In one day I can have 20 ocurrencies and in 
the following day I can have the double. ts datatype must have regular time 
spaces. What is the best way to put the data if I want to use forecasting 
methods as Holt-Winters, NN or SVM? To put data and time in different 
variables? If in one variable it would be of Date datatype?

Thank you for any help.

Joao
