Thanks Daniel for your reply
However I get these warnings even I start with a fresh R session and remove
all objects (including hidden ones) before executing the mentioned codes
I also tried reinstalling these libraries including zoo and xts libraries,
but the problem continues
I guess this is a generic problem when we load two libraries with same
defined class names
Any idea ?
