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.

Value

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