     ...: R objects which are coerced to character strings,
          concatenated, and printed, with the remaining
          arguments controlling the output.

    file: character string naming the file to print to.  If
          `""', `cat' prints to the standard output.

     sep: character string to insert between the objects to
          print.

    fill: a logical or numeric controlling how the output is
          broken into successive lines.  If `FALSE', 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.

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

  append: if `TRUE', output will be appended to `file'; oth-
          erwise, it will overwrite the contents of `file'.

_V_a_l_u_e:

     `cat' converts its arguments to character strings, con-
     catenates them, separating them by the given `sep='
     string, and then prints them.

     `cat' is useful for producing output in user defined
     functions.
