Data frame of log data. Rows are converted to <code>ndjson</code> entries,
with the columns as the fields.

Log file to write to. Defaults to currently-configured log
file.

logfile

overwrite


An effortless 'ndjson' (newline-delimited 'JSON') logger, with two primary
log-writing interfaces. It provides a set of wrappings for base R's
message(), warning(), and stop() functions that maintain identical
functionality, but also log the handler message to an 'ndjson' log file.
'loggit' also exports its internal 'loggit()' function for powerful and
configurable custom logging. No change in existing code is necessary to use
this package, and should only require additions to fully leverage the power
of the logging system. 'loggit' also provides a log reader for reading an
'ndjson' log file into a data frame, log rotation, and live echo of the
'ndjson' log messages to terminal 'stdout' for log capture by external
systems (like containers). 'loggit' is ideal for Shiny apps, data pipelines,
modeling work flows, and more. Please see the vignettes for detailed example
use cases.
