Add a variable to an Echoview file

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.

Value

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

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.

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'
