sprinkle_width: Adjust Table Cell Width

Description

Customize the width of a cell in a table. This may be done to improve the appearance of cells with long text.

Usage

sprinkle_width(
  x,
  rows = NULL,
  cols = NULL,
  width = NULL,
  width_units = NULL,
  part = c("body", "head", "foot", "interfoot", "table"),
  fixed = FALSE,
  recycle = c("none", "rows", "cols", "columns"),
  ...
)
# S3 method for default
sprinkle_width(
  x,
  rows = NULL,
  cols = NULL,
  width = NULL,
  width_units = NULL,
  part = c("body", "head", "foot", "interfoot", "table"),
  fixed = FALSE,
  recycle = c("none", "rows", "cols", "columns"),
  ...
)
# S3 method for dust_list
sprinkle_width(
  x,
  rows = NULL,
  cols = NULL,
  width = NULL,
  width_units = NULL,
  part = c("body", "head", "foot", "interfoot", "table"),
  fixed = FALSE,
  recycle = c("none", "rows", "cols", "columns"),
  ...
)

Arguments

x

An object of class dust

rows

Either a numeric vector of rows in the tabular object to be modified or an object of class call. When a call, generated by quote(expression), the expression resolves to a logical vector the same length as the number of rows in the table. Sprinkles are applied to where the expression resolves to TRUE.

cols

Either a numeric vector of columns in the tabular object to be modified, or a character vector of column names. A mixture of character and numeric indices is permissible.

width

numeric(1). Gives the width of the cell.

width_units

character(1). Gives the units for width. One of c("pt", "px", "cm", "in", "%")

part

A character string denoting which part of the table to modify.

fixed

logical(1) indicating if the values in rows and cols should be read as fixed coordinate pairs. By default, sprinkles are applied at the intersection of rows and cols, meaning that the arguments do not have to share the same length. When fixed = TRUE, they must share the same length.

recycle

A character one that determines how sprinkles are managed when the sprinkle input doesn't match the length of the region to be sprinkled. By default, recycling is turned off. Recycling may be performed across rows first (left to right, top to bottom), or down columns first (top to bottom, left to right).

...

Additional arguments to pass to other methods. Currently ignored.

Functional Requirements

  1. Correctly reassigns the appropriate elements of width and width_units columns in the table part.

  2. Casts an error if x is not a dust object.

  3. Casts an error if width is not numeric

  4. Casts an error if width_units is not one of c("px", "pt", "in", "cm", "%").

  5. Casts an error if part is not one of "body", "head", "foot", or "interfoot"

  6. Casts an error if fixed is not a logical(1)

  7. Casts an error if recycle is not one of "none", "rows", or "cols"

  8. Casts an error if recycle = "none" and width does not have length 1.

  9. Correctly assigns values when recycle is not "none" and multiple values are given.

  10. Quietly accepts only the first value in width_units when recycle = "none".

The functional behavior of the fixed and recycle arguments is not tested for this function. It is tested and validated in the tests for index_to_sprinkle.

Details

This sprinkle is only recognized by HTML and LaTeX. All of the width_units values are recognized by HTML. For LaTeX, "px" is converted to "pt".
