Use message to print a clean square data structure

Sends to message, but in a structured way so that a data.frame-like can be cleanly sent to messaging.

messageDF(
  df,
  round,
  colour = NULL,
  colnames = NULL,
  appendLF = TRUE,
  verbose = getOption("reproducible.verbose"),
  verboseLevel = 1
)

Arguments

df: A data.frame, data.table, matrix
round: An optional numeric to pass to round
colour: Passed to getFromNamespace(colour, ns = "crayon"), so any colour that crayon can use
colnames: Logical or NULL. If TRUE, then it will print column names even if there aren't any in the df (i.e., they will) be V1 etc., NULL will print them if they exist, and FALSE which will omit them.
appendLF: logical: should messages given as a character string have a newline appended?
verbose: Numeric, -1 silent (where possible), 0 being very quiet, 1 showing more messaging, 2 being more messaging, etc. Default is 1. Above 3 will output much more information about the internals of Caching, which may help diagnose Caching challenges. Can set globally with an option, e.g., options('reproducible.verbose' = 0) to reduce to minimal
verboseLevel: The numeric value for this message* call, equal or above which verbose must be. The higher this is set, the more unlikely the call will show a message.

Used for side effects. This will produce a message of a structured data.frame.
