How to turn off warnings about class name conflicts
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 ?

Hi, I am using two packages (quantmod and FRAPO) Quantmod and FRAPO both have a class names "zoo" R is displaying the following warning when I manipulate an object of class zoo: Found more than one class "zoo" in cache; using the first, from namespace 'quantmod' Also defined by ?FRAPO? The warning is displayed every time I manipulate a zoo object and becomes pretty annoying. I searched for a solution but couldn't found. A related but unanswered question is here: http://r.789695.n4.nabble.com/setOldClass-quot-xts-quot-td4714332.html How can I turn off the warning?

I tried your example (in a clean session) under R-3.4.3 from CRAN and Microsoft R Open 3.4.3.0 and did not get the message you are getting. I suspect you have something in your workspace that is causing the problem. Dan -- Daniel Nordlund Port Townsend, WA USA
