Printing tibbles
One of the main features of the tbl_df class is the printing:
Tibbles only print as many rows and columns as fit on one screen, supplemented by a summary of the remaining rows and columns.
Tibble reveals the type of each column, which keeps the user informed about
whether a variable is, e.g., <chr> or <fct> (character versus factor).
Printing can be tweaked for a one-off call by calling print() explicitly
and setting arguments like n and width. More persistent control is
available by setting the options described below.
See also vignette("digits", package = "pillar") for a comparison to base options,
and num() and char() for creating columns with custom formatting options.
As of tibble 3.1.0, printing is handled entirely by the pillar package.
If you implement a package that extend tibble,
the printed output can be customized in various ways.
See vignette("extending", package = "pillar") for details.
## S3 method for class 'tbl_df' print(x, ..., n = NULL, width = NULL, n_extra = NULL) ## S3 method for class 'tbl_df' format(x, ..., n = NULL, width = NULL, n_extra = NULL)
x |
Object to format or print. |
... |
Other arguments passed on to individual methods. |
n |
Number of rows to show. If |
width |
Width of text output to generate. This defaults to |
n_extra |
Number of extra columns to print abbreviated information for,
if the width is too small for the entire tibble. If |
The following options control printing of tbl and tbl_df objects:
tibble.print_max: Row number threshold: Maximum number of rows printed.
Set to Inf to always print all rows. Default: 20.
tibble.print_min: Number of rows printed if row number threshold is
exceeded. Default: 10.
tibble.width: Output width. Default: NULL (use width option).
tibble.max_extra_cols: Number of extra columns printed in reduced form.
Default: 100.
The output uses color and highlighting according to the "cli.num_colors" option.
Set it to 1 to suppress colored and highlighted output.
pillar.bold: Use bold font, e.g. for column headers? This currently
defaults to FALSE, because many terminal fonts have poor support for
bold fonts.
pillar.subtle: Use subtle style, e.g. for row numbers and data types?
Default: TRUE.
pillar.subtle_num: Use subtle style for insignificant digits? Default:
FALSE, is also affected by the pillar.subtle option.
pillar.neg: Highlight negative numbers? Default: TRUE.
pillar.sigfig: The number of significant digits that will be printed and
highlighted, default: 3. Set the pillar.subtle option to FALSE to
turn off highlighting of significant digits.
pillar.min_title_chars: The minimum number of characters for the column
title, default: 15. Column titles may be truncated up to that width to
save horizontal space. Set to Inf to turn off truncation of column
titles.
pillar.min_chars: The minimum number of characters wide to
display character columns, default: 0. Character columns may be
truncated up to that width to save horizontal space. Set to Inf to
turn off truncation of character columns.
pillar.max_dec_width: The maximum allowed width for decimal notation,
default 13.
