Functions to emit logging messages.

These functions accept a string and emit it through logging mechanisms, either to the console or a file, as configured.

logtrace(...)

logdebug(...)

loginfo(...)

logwarn(...)

logerror(...)

logfatal(...)

Arguments

message	A vector of string arguments.
name	An optional argument called which specifies that this logging message is part of the overall package. This is used to turn change logging level separately for a part of the package.

Value

Nothing is returned.

Details

The functions emit at different levels, from most-detailed to least-detailed: trace, debug, info, warn, error, fatal. An error can be non-fatal if the application has fallback behavior. A warning will show up in the log file. Info messages are meant for the user during normal operation. Debug messages are normally off but are left in the code. Trace messages are for automated processing, such as entry and exit of functions. These are often not left in code. None of the logging functions are exported from the package because they are not meant for users. They are for use inside the package because they use the package's logging namespace to emit messages.
