as_fc: as_fc

Description

This function allows to initialize a flow chart given any database. It will create a fc object showing the number of rows of the database. If a database is not available, the user can instead directly enter the number of rows in the study.

Usage

as_fc(
  .data = NULL,
  N = NULL,
  label = "Initial dataframe",
  text_pattern = "{label}\n{N}",
  just = "center",
  text_color = "black",
  text_fs = 8,
  text_fface = 1,
  text_ffamily = NA,
  text_padding = 1,
  bg_fill = "white",
  border_color = "black",
  width = NA,
  height = NA,
  hide = FALSE,
  title = NULL,
  x_title = 0.1,
  text_color_title = "black",
  text_fs_title = 10,
  text_fface_title = 1,
  text_ffamily_title = NA,
  text_padding_title = 0.6,
  bg_fill_title = "#B3D1FF",
  border_color_title = "black",
  width_title = NA,
  height_title = NA
)

Value

List with the dataset and the initialized flowchart parameters.

Arguments

.data: Data frame to be initialised as a flowchart.
N: Number of rows of the study in case .data is NULL.
label: Character or expression with the text that will be shown in the box.
text_pattern: Character or expression defining the structure that will have the text in each of the boxes. It recognizes label, n, N and perc within brackets. For default it is "{label}\n {n}". If text_pattern or label is an expression, the label is always placed at the beginning of the pattern, followed by a line break where the structure specified by text_pattern is placed.
just: Justification for the text: left, center or right. Default is center.
text_color: Color of the text. It is "black" by default. See the col parameter for gpar.
text_fs: Font size of the text. It is 8 by default. See the fontsize parameter for gpar.
text_fface: Font face of the text. It is 1 by default. See the fontface parameter for gpar.
text_ffamily: Changes the font family of the text. Default is NA. See the fontfamily parameter for gpar.
text_padding: Changes the text padding inside the box. Default is 1. This number has to be greater than 0.
bg_fill: Box background color. It is white by default. See the fill parameter for gpar.
border_color: Box border color. It is "black" by default. See the col parameter for gpar.
width: Width of the box. If NA, it automatically adjusts to the content (default). Must be an object of class unit or a number between 0 and 1.
height: Height of the box. If NA, it automatically adjusts to the content (default). Must be an object of class unit or a number between 0 and 1.
hide: Logical value to hide the initial box or not. Default is FALSE. hide = TRUE can only be combined with fc_split().
title: Add a title box to the initial box. Default is NULL.
x_title: x-coordinate of the title box. Default is 0.1 (placed in the left).
text_color_title: Color of the title text. It is "black" by default.
text_fs_title: Font size of the title text. It is 8 by default.
text_fface_title: Font face of the title text. It is 1 by default. See the fontface parameter for gpar.
text_ffamily_title: Changes the font family of the title text. Default is NA. See the fontfamily parameter for gpar.
text_padding_title: Changes the title text padding inside the box. Default is 1. This number has to be greater than 0.
bg_fill_title: Title box background color. It is "white" by default.
border_color_title: Title box border color. It is "black" by default.
width_title: Width of the title box. If NA, it automatically adjusts to the content (default). Must be an object of class unit or a number between 0 and 1.
