val |
logical/numeric value that sets the verbosity level. |
global |
logical that indicates if the verbose level of all log handlers should be set to val. |
level |
verbosity level threshold (numeric value) above which the
message should be printed out.
This threshold is compared with the current verbosity level as returned by

... |
parts of a character message that are concatenated and passed to the current logger's write function. |
appendLF |
logical indicating if an endline character should be appended at the end of the message. |

force |
logical that indicates if one should output messages or return a non null logger, even if the verbose mode is not high enough. |
the old verbose level
lsilent: tells if all verbose messages are silenced.
is.verbose: tells if verbosity is on, i.e. at level greater than 0.
lmessage: prints out a message (on sdtout) if the verbosity level is greater than a
given value.
vmessage: prints out a log message (at level 1) using the current logger,
typically on stdout.
It is a shortcut for lmessage(1L, ...).
log_append: directly appends some message to the current log line.
