Transform rtable to a list of matrices which can be used for outputting

Source: R/rlistings.R
matrix_form-listing_df-method.Rd

Although rtables are represented as a tree data structure when outputting the table to ASCII or HTML, it is useful to map the rtable to an in-between state with the formatted cells in a matrix form.

Usage 

# S4 method for class 'listing_df'
matrix_form(
  obj,
  indent_rownames = FALSE,
  expand_newlines = TRUE,
  fontspec = font_spec,
  col_gap = 3L
)

Arguments

obj

(ANY)
object to be transformed into a ready-to-render form (a MatrixPrintForm object).

indent_rownames

(flag)
silently ignored, as listings do not have row names nor indenting structure.

expand_newlines

(flag)
this should always be TRUE for listings. We keep it for debugging reasons.

fontspec

(font_spec)
a font_spec object specifying the font information to use for calculating string widths and heights, as returned by font_spec().

col_gap

(numeric(1))
the gap to be assumed between columns, in number of spaces with font specified by fontspec.

Value

a formatters::MatrixPrintForm object.
