pillar_shaft: Column data

In hadley/pillar: Coloured Formatting for Columns

Column data

Description

Internal class for formatting the data for a column. pillar_shaft() is a coercion method that must be implemented for your data type to display it in a tibble.

This class comes with a default method for print() that calls format(). If print() is called without width argument, the natural width will be used when calling format(). Usually there's no need to implement this method for your subclass.

Your subclass must implement format(), the default implementation just raises an error. Your format() method can assume a valid value for the width argument.

Usage

pillar_shaft(x, ...)

## S3 method for class 'pillar_shaft'
print(x, width = NULL, ...)

## S3 method for class 'pillar_shaft'
format(x, width, ...)

## S3 method for class 'logical'
pillar_shaft(x, ...)

## S3 method for class 'numeric'
pillar_shaft(x, ..., sigfig = NULL)

## S3 method for class 'Date'
pillar_shaft(x, ...)

## S3 method for class 'POSIXt'
pillar_shaft(x, ...)

## S3 method for class 'character'
pillar_shaft(x, ..., min_width = NULL)

## S3 method for class 'glue'
pillar_shaft(x, ..., min_width = NULL, na_indent = 0L, shorten = NULL)

## S3 method for class 'list'
pillar_shaft(x, ...)

## S3 method for class 'factor'
pillar_shaft(x, ...)

## S3 method for class 'AsIs'
pillar_shaft(x, ...)

## Default S3 method:
pillar_shaft(x, ...)

Arguments

x	A vector to format
...	Arguments passed to methods.
width	Width for printing and formatting.
sigfig	Deprecated, use num() or set_num_opts() on the data instead.
min_width	Deprecated, use char() or set_char_opts() on the data instead.
na_indent	Indentation of NA values.
shorten	How to abbreviate the data if necessary: "back" (default): add an ellipsis at the end "front": add an ellipsis at the front "mid": add an ellipsis in the middle "abbreviate": use abbreviate()

Details

The default method will currently format via format(), but you should not rely on this behavior.

Examples

pillar_shaft(1:3)
pillar_shaft(1.5:3.5)
pillar_shaft(NA)
pillar_shaft(c(1:3, NA))
