Concatenate and Print

Same as base::cat() but with an additional argument end, which gets printed after all other elements. Inspired by pythons print command.

Usage

cat2(
  ...,
  sep = " ",
  end = "\n",
  file = "",
  append = FALSE,
  fill = FALSE,
  labels = NULL
)

Arguments

...

R objects (see 'Details' for the types of objects allowed).

sep

a character vector of strings to append after each element.

end

a string to print after all other elements.

file

A connection, or a character string naming the file to print to. If "" (the default), cat2 prints to the standard output connection, the console unless redirected by sink.

append

logical. Only used if the argument file is the name of file (and not a connection or "|cmd"). If TRUE output will be appended to file; otherwise, it will overwrite the contents of file.

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. Linefeeds are only inserted between elements, strings wider than fill are not wrapped. Non-positive fill values are ignored, with a warning.

labels

character vector of labels for the lines printed. Ignored if fill is FALSE.

Value

No return value, called for side effects

Examples

x <- 1
cat("x:", x, "\n") # prints 'Number: 1 \n' (with a space between 1 and \n)
#> x: 1 
cat2("x:", x) # prints 'Number: 1\n'  (without space)
#> x: 1
