coredata.xts: Extract/Replace Core Data of an xts Object

Description

Mechanism to extract and replace the core data of an xts object.

Usage

## S3 method for class 'xts':
coredata(x, ...)
xcoredata(x,...)
xcoredata(x) <- value

Arguments

x

an xts object

value

non-core attributes to assign

...

further arguments [unused]

Value

• Returns either a matrix object for coredata, or a list of named attributes.

  The replacement functions are called for their side-effects.

Details

Extract coredata of an xts object - removing all attributes except dim and dimnames and returning a matrix object with rownames converted from the index of the xts object.

xcoredata is the functional complement to coredata, returning all of the attributes normally removed by coredata. Its purpose, along with the replacement function xcoredata<- is primarily for use by developers using xts to allow for internal replacement of values removed during use of non xts-aware functions.
