xtsAttributes(x, user=NULL)

xtsAttributes(x) <- value

Arguments

x

an xts object

user

logical; should user-defined attributes be returned? The default of NULL returns all xts attributes.

value

a list of new name=value attributes

Details

Since xts objects are S3 objects with special attributes, a method is necessary to properly assign and view the user-added attributes.

A call to attributes from the base package will return all attributes, including those specific to the xts class.

Value

A named list of user settable attributes.
