Get width and height of the forestplot — get

get_wh can be used to find the correct width and height of the forestplot for saving, as the width and height are difficult to estimate otherwise.

Usage

get_wh(plot, unit = c("in", "cm", "mm"))

Arguments

plot: A forest plot object.
unit: Unit for the returned width and height. One of "in", "cm", or "mm".

Value

A named vector of width and height

Details

This is the natural size of the plot, where every column and row fits its content. By default a plot drawn in a larger space keeps this size and is centred. With fit of forest_style the CI columns, and the rows if asked for, take the space instead.

Examples

if (FALSE) { # \dontrun{
 dt <- read.csv(system.file("extdata", "example_data.csv", package = "forestploter"))
 dt <- dt[1:6,1:6]

 dt$` ` <- paste(rep(" ", 20), collapse = " ")

 p <- forest(dt[,c(1:3, 7)],
             est = dt$est,
             lower = dt$low,
             upper = dt$hi,
             ci_column = 4)

# get_wh example
p_wh <- get_wh(p)
pdf('test.pdf',width = p_wh[1], height = p_wh[2])
plot(p)
dev.off()
} # }
