flog.threshold (Package: futile.logger) : Get and set the threshold for a logger

The threshold affects the visibility of a given logger. When a log statement is called, e.g. flog.debug('foo'), futile.logger compares the threshold of the logger with the level implied in the log command (in this case DEBUG). If the log level is at or higher in priority than the logger threshold, a message will print. Otherwise the command will silently return.

futile.logger-package (Package: futile.logger) : A Logging Utility for R

This package implements a logging system inspired by log4j. The basic idea of layouts, appenders, and loggers is faithful to log4j, while the implementation and idiom is all R. This means that support for hierarchical loggers, custom appenders, custom layouts is coupled with a simple and intuitive functional syntax.
