Outputs the objects, concatenating the representations. cat performs much less conversion than print.
cat(… , file = "", sep = " ", fill = FALSE, labels = NULL,
append = FALSE)| Parameter | Description |
|---|---|
… |
R objects (see ‘Details’ for the types of objects allowed). |
file |
A connection, or a character string naming the file to print to. If "" (the default), cat prints to the standard output connection, the console unless redirected by sink. If it is "|cmd", the output is piped to the command given by cmd, by opening a pipe connection. |
sep |
a character vector of strings to append after each element. |
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. 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. |
# NOT RUN {
iter <- stats::rpois(1, lambda = 10)
## print an informative message
cat("iteration = ", iter <- iter + 1, "\n")
## 'fill' and label lines:
cat(paste(letters, 100* 1:26), fill = TRUE, labels = paste0("{", 1:10, "}:"))
# }
