echo_msg {comFuncs} R Documentation

## Echo message

### Description

This method displays or writes the message based on debug level. The filehandler is provided through environment variable 'log_fn', and the outputs are written to the file. This method will display message or a hash array based on debug level ('d_level'). If 'd_level' is set to '0', no message or array will be displayed. If 'd_level' is set to '2', it will only display the message level (lvl) is less than or equal to '2'. If you call this method without providing a message level, the message level (lvl) is default to '0'. Of course, if no message is provided to the method, it will be quietly returned. If 'd_level' is set to '1', all the messages with default message level, i.e., 0, and '1' will be displayed. The higher level messages will not be displayed.
