Log

A log file to save attributes of an object. The saved file uses the csv standard: The first line contains the attribute names and the following lines contains values according to the calls to notify().

Arguments

• file: A string with the file name to be saved. The default value is "result.csv".
• overwrite: A boolean value indicating whether the file should be overwritten. The default value is true.
• select: A vector of strings with the name of the attributes to be observed. If it is only a single value then it can also be described as a string. As default, it selects all the user-defined attributes of an object. In the case of Society, if it does not have any numeric attributes then it will use the number of agents in the Society as attribute.
• separator: A string with the separator. The default value is ",".
• target: An Agent, Cell, CellularSpace, Society.

Usage

agent = Agent{
    age = 3
}

    target = agent,
    file = "agent.csv",
    separator = ";"
}
