Arguments

x

(listing_df)
the listing.

widths

(numeric or NULL)
Proposed widths for the columns of x. The expected length of this numeric vector can be retrieved with ncol(x) + 1 as the column of row names must also be considered.

tf_wrap

(flag)
whether the text for title, subtitles, and footnotes should be wrapped.

max_width

(integer(1), string or NULL)
width that title and footer (including footnotes) materials should be word-wrapped to. If NULL, it is set to the current print width of the session (getOption("width")). If set to "auto", the width of the table (plus any table inset) is used. Parameter is ignored if tf_wrap = FALSE.

...

additional parameters passed to formatters::toString().

i

(any)
object passed to base [ methods.

j

(any)
object passed to base [ methods.

drop

For matrices and arrays. If TRUE the result is coerced to the lowest possible dimension (see the examples). This only works for extracting elements, not for the replacement. See drop for further details.

obj

(listing_df)
the listing.

value

typically an array-like R object of a similar class as x.

Value

• Accessor methods return the value of the aspect of obj.

• Setter methods return obj with the relevant element of the listing updated.

Examples

lsting <- as_listing(mtcars)
main_title(lsting) <- "Hi there"

main_title(lsting)
