Functional Details

This module allows you to replace or insert a member of an existing group.

data	is the group to be modified
operation	is the operation to perform on the specified member of data. If data is a series group, then operation must be one of "insert before", "replace", "insert after", or "delete". If data is any other kind of group, then operation must be one of "insert", "replace", "delete". Note that for most applications, the order of members in a group is not important, and the order of members in a group is not guaranteed to be maintained by modules in Data Explorer unless the group is a Series.
id	is the index (from 0 to n-1, where n is the number of members of data) or name of an existing member of data
newmember	is the new or replacement object to be placed in data
newtag	is the series position or member name for newmember. If data is a series, this parameter is required.

Components

This module does not modify any components of the input data.
