Description

Concatenates object values into a string with each value separated by a comma and the last value separated by a conjunction.

Usage

cc(
  x,
  conj = ", ",
  sep = ", ",
  brac = if (is.character(x) || is.factor(x)) "'" else "",
  ellipsis = 10L,
  chk = TRUE
)

Arguments

`x`	The object to concatenate.
`conj`	A string of the conjunction to separate the last value by.
`sep`	A string of the separator.
`brac`	A string to brac the values by.
`ellipsis`	A numeric scalar of the maximum number of values to display before using an ellipsis.
