What is class(x) ?? I think you need to (re?) learn about S3 classes, which can in general be vectors. See ?class (the S3 portion) or any tutorial on S3 classes in R. I have no idea what you are trying to do, but I *suspect* it may be accomplished through S3 inheritance rather than changing the class vector. That is just a guess, however. -- Bert On Sat, Jun 17, 2023 at 10:27 AM akshay kulkarni <akshay...@hotmail.com<mailto:akshay...@hotmail.com>> wrote: Dear members, AN update: I have changed the if clause to: if(class(x)[1] == "xts") || class(x)[2] == "zoo") {code} but am bootless.....
