pillar_shaft: Column data

In pillar: Coloured Formatting for Columns

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 'pillar_vertical'
pillar_shaft(x, ..., min_width = NULL, na_indent = 0L)

## 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	Minimum number of significant figures to display, default: 3. Numbers larger than 1 will potentially show more significant figures than this.
min_width	Minimum number of characters to display, unless the string fits a shorter width.
na_indent	Indentation of NA values.

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))
