EVAddVariable: Add a variable to an Echoview file

In AustralianAntarcticDivision/EchoviewR: Control of Echoview via COM

Add a variable to an Echoview file

Description

This function adds an Echoview variable to an existing Echoview file. The variable is added by specifying the existing variable to which the new variable is added and the new variable type.

Usage

EVAddVariable(EVFile, acoVarName, EOperator, addedVarName = NULL)

Arguments

EVFile	Echoview file COM object
acoVarName	The acoustic variable name to which a new variable will be added.
EOperator	The 'EOperator' number of the variable to add. See notes
addedVarName	=NULL. Name of the added variable.

Details

The new variable type is specifed using the variable-specific 'EOperator' integer. For example, the 'Ping subset' operator 'EOperator' is 62. See Echoview help for details.

Value

list with three elements: $varObj acoustic variable COM object; $objName new name of the variable object; $msg message vector

Note

This function is under development. We hope to add an 'EOperator' look up table sp that the type of variable to add can be specified by its character name, rather than 'EOperator'
