printf

Functions for Formatted Output and Conditions

catf(), messagef(), warningf() and stopf() are wrappers around base::cat(), base::message(), base::warning() and base::stop(), respectively. The call is not included for warnings and errors.

catf(msg, ..., file = "", wrap = FALSE)

messagef(msg, ..., wrap = FALSE)

warningf(msg, ..., wrap = FALSE)

stopf(msg, ..., wrap = FALSE)

`msg`	(`character(1)`) Format string passed to `base::sprintf()`.
`...`	(`any`) Arguments passed down to `base::sprintf()`.
`file`	(`character(1)`) Passed to `base::cat()`.
`wrap`	(`integer(1)` \| `logical(1)`) If set to a positive integer, `base::strwrap()` is used to wrap the string to the provided width. If set to `TRUE`, the width defaults to `0.9 * getOption("width")`. If set to `FALSE`, wrapping is disabled (default). If wrapping is enabled, all whitespace characters (`[[:space:]]`) are converted to spaces, and consecutive spaces are converted to a single space.

messagef("
  This is a rather long %s
  on multiple lines
  which will get wrapped.
", "string", wrap = 15)
