table_shell: Table shells

In Roche/rtables: Reporting Tables

Table shells

Description

A table shell is a rendering of the table which maintains the structure, but does not display the values, rather displaying the formatting instructions for each cell.

Usage

table_shell(
  tt,
  widths = NULL,
  col_gap = 3,
  hsep = default_hsep(),
  tf_wrap = FALSE,
  max_width = NULL
)

table_shell_str(
  tt,
  widths = NULL,
  col_gap = 3,
  hsep = default_hsep(),
  tf_wrap = FALSE,
  max_width = NULL
)

Arguments

tt	(TableTree or related class) a TableTree object representing a populated table.
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.
col_gap	(numeric(1)) space (in characters) between columns.
hsep	(string) character to repeat to create header/body separator line. If NULL, the object value will be used. If " ", an empty separator will be printed. See default_hsep() for more information.
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.

Value

• table_shell returns NULL, as the function is called for the side effect of printing the shell to the console.

• table_shell_str returns the string representing the table shell.

value_formats() for a matrix of formats for each cell in a table.

Examples

library(dplyr)

iris2 <- iris %>%
  group_by(Species) %>%
  mutate(group = as.factor(rep_len(c("a", "b"), length.out = n()))) %>%
  ungroup()

lyt <- basic_table() %>%
  split_cols_by("Species") %>%
  split_cols_by("group") %>%
  analyze(c("Sepal.Length", "Petal.Width"), afun = list_wrap_x(summary), format = "xx.xx")

tbl <- build_table(lyt, iris2)
table_shell(tbl)
