Propose column widths based on the MatrixPrintForm of an object

Row names are also considered a column for the output.

Usage

propose_column_widths(
  x,
  indent_size = 2,
  fontspec = font_spec(),
  round_type = c("iec", "sas")
)

Arguments

x: (ANY)
a MatrixPrintForm object, or an object with a matrix_form method.
indent_size: (numeric(1))
indent size, in characters. Ignored when x is already a MatrixPrintForm object in favor of information there.
fontspec: (font_spec)
a font_spec object specifying the font information to use for calculating string widths and heights, as returned by font_spec().
round_type: ("iec" or "sas")
the type of rounding to perform. iec, the default, peforms rounding compliant with IEC 60559 (see details), while sas performs nearest-value rounding consistent with rounding within SAS.

Value

A vector of column widths based on the content of x for use in printing and pagination.
