R Documentation

Printing Data Frames

Description

Print a data frame.

Usage

## S3 method for class 'data.frame'
print(x, ..., digits = NULL,
      quote = FALSE, right = TRUE, row.names = TRUE, max = NULL)

Arguments

`x`	object of class `data.frame`.
`...`	optional arguments to `print` methods.
`digits`	the minimum number of significant digits to be used: see `print.default`.
`quote`	logical, indicating whether or not entries should be printed with surrounding quotes.
`right`	logical, indicating whether or not strings should be right-aligned. The default is right-alignment.
`row.names`	logical (or character vector), indicating whether (or what) row names should be printed.
`max`	numeric or `NULL`, specifying the maximal number of entries to be printed. By default, when `NULL`, `getOption("max.print")` used.

Details

This calls format which formats the data frame column-by-column, then converts to a character matrix and dispatches to the print method for matrices.

When quote = TRUE only the entries are quoted not the row names nor the column names.

Examples

(dd <- data.frame(x = 1:8, f = gl(2,4), ch = I(letters[1:8])))
     # print() with defaults
print(dd, quote = TRUE, row.names = FALSE)
     # suppresses row.names and quotes all entries
