Concatenate and Print with No Separator

Outputs the objects, concatenating the representations with no separator.

Usage

cat0(..., file = "", fill = FALSE, labels = NULL, append = FALSE)

Arguments

...

R objects (see cat for the types of objects allowed).

file

a connection, or a character string naming the file to print to. If "" (the default), cat0 prints to the standard output connection, the console unless redirected by sink.

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.

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.

Value

None (invisible NULL).

Details

All arguments are passed to a call to cat with sep set to "".
