Switch progress messages on or off

Large tables take tens of minutes, and the pipeline reports every stage as it runs: stage name, input and output counts, elapsed time. Messages go through message() as single lines, with no progress bar that redraws itself, so that a scheduled job (Rscript in batch) produces a readable log. suppressMessages() works too; this function exists to switch them off persistently, without wrapping every call. The verbose key of scr_config() has the same effect per run.

Usage

scr_verbose(on = NULL)

Arguments

on

TRUE to switch on, FALSE to switch off, NULL (default) to query the current state only.

Value

The verbosity state in force before the call, invisibly, so that old <- scr_verbose(FALSE); ...; scr_verbose(old) restores it.

Other configuration: scr_config(), scr_config_keys(), scr_presets()

Examples

old <- scr_verbose(FALSE)   # silence, keeping the previous state
scr_verbose(old)            # restore
scr_verbose()               # query
