Format and Print — catf • toscutil

Same as cat(sprintf(fmt, ...))

Usage

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

fmt: A character vector of format strings, each of up to 8192 bytes.
...: Up to 100 values to be passed into fmt. Only logical, integer, real and character vectors are supported, but some coercion will be done: see the Details section of base::sprintf().
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.

No return value, called for side effects

catf("A%dB%sC", 2, "asdf") # prints "A2BasdfC"
#> A2BasdfC
