Re: [R] [R-SIG-Finance] How to separate date and time into different columns?

A note about xts: The time class layer is abstracted from the implementation. This allows for some very time specific manipulation without having to manage the underlying details. Take a look at the xts docs and vignette. Also, the functions .indexmon .indexyear etc correspond to the POSIX
