copy.attributes: Copy Attributes

In magclass: Data Class and Tools for Handling Spatial-Temporal Data

Copy Attributes

Description

This function copies attributes from one object and assigns them to another.

Usage

copy.attributes(
  from,
  to,
  delete = c("names", "row.names", "class", "dim", "dimnames"),
  delete2 = NULL
)

copy.attributes(
  to,
  delete = c("names", "row.names", "class", "dim", "dimnames"),
  delete2 = NULL
) <- value

Arguments

from	object from which the attributes should be taken
to	object to which the attributes should be written
delete	attributes which should not be copied. By default this are class specific attributes which might cause problems if copied to another object. But you can add or remove attributes from the vector.
delete2	Identical to delete and just added for convenience for the case that you want to delete additional attributes but do not want to repeat the vector given in delete. In the function both vectors, delete and delete2, are just merged to one deletion vector.
value	Same as "from" (object from which the attributes should be taken)

Functions

• copy.attributes( to, delete = c("names", "row.names", "class", "dim", "dimnames"), delete2 = NULL ) <- value: assign attributes from object "value"
