Layout with 1 column and zero rows

Usage

basic_table(
  title = "",
  subtitles = character(),
  main_footer = character(),
  prov_footer = character(),
  show_colcounts = FALSE,
  colcount_format = "(N=xx)",
  inset = 0L
)

Arguments

title

character(1). Main title (main_title()) is a single string. Ignored for subtables.

subtitles

character. Subtitles (subtitles()) can be vector of strings, where every element is printed in a separate line. Ignored for subtables.

main_footer

character. Main global (non-referential) footer materials (main_footer()). If it is a vector of strings, they will be printed on separate lines.

prov_footer

character. Provenance-related global footer materials (prov_footer()). It can be also a vector of strings, printed on different lines. Generally should not be modified by hand.

show_colcounts

logical(1). Should column counts be displayed in the resulting table when this layout is applied to data

colcount_format

character(1). Format for use when displaying the column counts. Must be 1d, or 2d where one component is a percent. See details.

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).

Value

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

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.

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 (subtitles()) and footers (main_footer() and prov_footer()) that spans 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
#>            all obs     
#> ———————————————————————
#> mean   34.2219101123596

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
