fp_decorate_graph: Decorate the graph

Description

Decorate the graph

Usage

fp_decorate_graph(
  x,
  box = NULL,
  right_bottom_txt = NULL,
  left_bottom_txt = NULL,
  right_top_txt = NULL,
  left_top_txt = NULL,
  grid = NULL,
  graph.pos = NULL
)

Value

The forestplot object with the extended decoration

Arguments

x

The forestplot object

box

Decorate the graph by framing it in a box. If provided TRUE it will simply frame the graph in a black box. If you provide a string it is assumed to be the color of the graph. Acceptable arguments are also gpar() and a grob object to draw.

right_bottom_txt

Text to appear at the right bottom of the graph. Can be decorated fp_txt_* functions.

left_bottom_txt

Text to appear at the left bottom of the graph. Can be decorated fp_txt_* functions.

right_top_txt

Text to appear at the right top of the graph. Can be decorated fp_txt_* functions.

left_top_txt

Text to appear at the left top of the graph. Can be decorated fp_txt_* functions.

grid

If you want a discrete gray dashed grid at the level of the ticks you can set this parameter to TRUE. If you set the parameter to a vector of values lines will be drawn at the corresponding positions. If you want to specify the gpar of the lines then either directly pass a gpar object or set the gp attribute e.g. attr(line_vector, "gp") <- gpar(lty = 2, col = "red")

graph.pos

The position of the graph element within the table of text. The position can be 1-(ncol(labeltext) + 1). You can also choose set the position to "left" or "right".
