Useful mainly in a script file to time, then log, each step (or process)
in the file.
timer(
process,
notes = NULL,
file = NULL,
name = NULL,
log = NULL,
time_df = NULL,
write_log = grepl("end", process)
)Character. Name of the process being timed.
Character. Any notes associated with the process.
Character. Name of the (script) file.
Character. Might be the same as process, or an element over
which process is being run. e.g. name could be a species name where the
same function is being run over many different species.
Character. Path to write the log file.
Object name or null for the initiation of a timer.
Write the log after this process. Default is only where process contains 'end'.
A dataframe (time_df), possibly with an additional row for the
current process. If write_log then log file is written.
Timer can be re-started by including 'start' in a process.
time_df <- timer("start script", file = "file 01", name = "example", log = "example.log")
Sys.sleep(1)
time_df <- timer("process 01", time_df = time_df)
Sys.sleep(1)
