copy_data

Context: data

Synopsis

Copy a data set by data ID to a new data ID (deep copy)

Syntax

copy_data( fromid, toid )

Description

The copy_data() function performs a deep copy operation in which one data set is fully copied to another.

fromid - the id of the source data set
toid - id of the destination data set

Example

sherpa> copy_data(2, "src")

The copy_data() function copies one data set to another, by data set ID. Here, the data contained in data set 2 is copied to data set "src".
