print {base}

R Documentation

Print Values

Description

print prints its argument and returns it invisibly (via invisible(x)). It is a generic function which means that new printing methods can be easily added for new classes.

Usage

print(x, ...)

print.factor(x, quote = FALSE, max.levels = NULL,
             width = getOption("width"), ...)

Arguments

x	an object used to select a method.
...	further arguments passed to or from other methods.
quote	logical, indicating whether or not strings should be printed with surrounding quotes.
max.levels	integer, indicating how many levels should be printed for a factor; if 0, no extra "Levels" line will be printed. The default, NULL, entails chosing max.levels such that the levels print on one line of width width.
width	only used when max.levels is NULL, see above.

Details

The default method, print.default has its own help page. Use methods("print") to get all the methods for the print generic.

print.factor allows some customization and is used for printing ordered factors as well.

See noquote as an example of a class whose main purpose is a specific print method.
