basic_table: Layout with 1 column and zero rows

In rtables: Reporting Tables

Layout with 1 column and zero rows

Description

Every layout must start with a basic table.

Usage

basic_table(
  title = "",
  subtitles = character(),
  main_footer = character(),
  prov_footer = character(),
  show_colcounts = NA,
  colcount_format = "(N=xx)",
  header_section_div = NA_character_,
  top_level_section_div = NA_character_,
  inset = 0L
)

Arguments

title	(string) single string to use as main title (formatters::main_title()). Ignored for subtables.
subtitles	(character) a vector of strings to use as subtitles (formatters::subtitles()), where every element is printed on a separate line. Ignored for subtables.
main_footer	(character) a vector of strings to use as main global (non-referential) footer materials (formatters::main_footer()), where every element is printed on a separate line.
prov_footer	(character) a vector of strings to use as provenance-related global footer materials (formatters::prov_footer()), where every element is printed on a separate line.
show_colcounts	(logical(1)) Indicates whether the lowest level of applied to data. NA, the default, indicates that the show_colcounts argument(s) passed to the relevant calls to ⁠split_cols_by*⁠ functions. Non-missing values will override the behavior specified in column splitting layout instructions which create the lowest level, or leaf, columns.
colcount_format	(string) format for use when displaying the column counts. Must be 1d, or 2d where one component is a percent. This will also apply to any displayed higher level column counts where an explicit format was not specified. Defaults to "(N=xx)". See Details below.
header_section_div	(string) string which will be used to divide the header from the table. See header_section_div() for the associated getter and setter. Please consider changing last element of section_div() when concatenating tables that require a divider between them.
top_level_section_div	(character(1)) if assigned a single character, the first (top level) split or division of the table will be highlighted by a line made of that character. See section_div for more information.
inset	(numeric(1)) number of spaces to inset the table header, table body, referential footnotes, and main_footer, as compared to alignment of title, subtitle, and provenance footer. Defaults to 0 (no inset).

Details

colcount_format is ignored if show_colcounts is FALSE (the default). When show_colcounts is TRUE, and colcount_format is 2-dimensional with a percent component, the value component for the percent is always populated with 1 (i.e. 100%). 1d formats are used to render the counts exactly as they normally would be, while 2d formats which don't include a percent, and all 3d formats result in an error. Formats in the form of functions are not supported for colcount format. See formatters::list_valid_format_labels() for the list of valid format labels to select from.

Value

A PreDataTableLayouts object suitable for passing to further layouting functions, and to build_table().

Note

• Because percent components in colcount_format are always populated with the value 1, we can get arguably strange results, such as that individual arm columns and a combined "all patients" column all list "100%" as their percentage, even though the individual arm columns represent strict subsets of the "all patients" column.

• Note that subtitles (formatters::subtitles()) and footers (formatters::main_footer() and formatters::prov_footer()) that span more than one line can be supplied as a character vector to maintain indentation on multiple lines.

Examples

lyt <- basic_table() %>%
  analyze("AGE", afun = mean)

tbl <- build_table(lyt, DM)
tbl

lyt2 <- basic_table(
  title = "Title of table",
  subtitles = c("a number", "of subtitles"),
  main_footer = "test footer",
  prov_footer = paste(
    "test.R program, executed at",
    Sys.time()
  )
) %>%
  split_cols_by("ARM") %>%
  analyze("AGE", mean)

tbl2 <- build_table(lyt2, DM)
tbl2

lyt3 <- basic_table(
  show_colcounts = TRUE,
  colcount_format = "xx. (xx.%)"
) %>%
  split_cols_by("ARM")
