vcat {madrat}

Tool: Verbosity Cat

Description

Function which returns information based on the verbosity setting

Usage

vcat(
  verbosity,
  ...,
  level = NULL,
  fill = TRUE,
  show_prefix = TRUE,
  logOnly = FALSE
)

Arguments

verbosity

The lowest verbosity level for which this message should be shown (verbosity = -1 means no information at all, 0 = only warnings, 1 = warnings and execution information, 2 = full information). If the verbosity is set to 0 the message is written as warning, if the verbosity is set higher than 0 it is written as a normal cat message.

...

The message to be shown

level

This argument allows to establish a hierarchy of print statements. The hierarchy is preserved for the next vcat executions. Currently this setting can have 4 states: NULL (nothing will be changed), 0 (reset hierarchies), "+" (increase hierarchy level by 1) and "-" (decrease hierarchy level by 1).

fill

a logical or (positive) numeric controlling how the output is broken into successive lines. If FALSE (default), only newlines created explicitly by "\n" are printed. Otherwise, the output is broken into lines with print width equal to the option width if fill is TRUE, or the value of fill if this is numeric. Non-positive fill values are ignored, with a warning.

show_prefix

a logical defining whether a content specific prefix (e.g. "NOTE") should be shown in front of the message or not. If prefix is not shown it will also not show up in official statistics.

logOnly

option to only log warnings and error message without creating warnings or errors (expert use only).
